🔌 CONVERT 24V DC TO AN ISOLATED 12V-CLASS SUPPLY

The Orion-Tr is designed for electrical systems where a nominal 24V DC source must operate equipment requiring a regulated 12V-class supply.

Input voltage range: 20V–35V DC

Nominal output voltage: 12.2V DC

Adjustable output range: 10V–15V DC

This allows compatible 12V equipment to operate from an appropriate 24V source while keeping the input and output circuits galvanically isolated.

⚠️ IMPORTANT: Confirm the required operating voltage of connected equipment before setting the converter output. Incorrect output voltage may damage connected electrical equipment.

---

🎛️ ADJUSTABLE 10–15V OUTPUT

Nominal output voltage:

12.2V DC

Output-voltage adjustment range:

10V–15V DC

Output-voltage tolerance:

±0.2V

The adjustable output provides flexibility for compatible electrical equipment requiring a particular regulated voltage within the supplied 10V to 15V range.

⚠️ IMPORTANT: Measure and confirm the converter output voltage before connecting sensitive equipment.

---

🛡️ GALVANICALLY ISOLATED INPUT & OUTPUT

Supplied galvanic isolation:

200V DC between input, output and case

This electrically separates the converter's input-side circuit from its output-side circuit rather than using a direct common electrical path.

Galvanic isolation can be useful in compatible commercial vehicle, marine, communications and industrial installations where electrical separation or independently referenced circuits are required.

⚠️ IMPORTANT: Confirm that the supplied 200V DC galvanic-isolation specification is appropriate for the requirements of your complete electrical system.

---

⚡ 30A CONTINUOUS OUTPUT AT 40°C

Continuous output current at nominal output voltage and 40°C:

30A

Maximum output current at nominal output voltage:

45A for 10 seconds

Short-circuit output current:

60A

The supplied 30A continuous-current specification should be used when determining normal sustained loads at the stated operating condition.

⚠️ IMPORTANT: The 45A maximum output applies for up to 10 seconds and must not be treated as a continuous-current rating.

⚠️ IMPORTANT: The 60A short-circuit output-current specification relates to the converter's short-circuit behaviour. It is not a normal appliance-load rating.

---

🔋 OUTPUT POWER & TEMPERATURE

Continuous output power at 25°C:

430W

Continuous output power at 40°C:

360W

The reduction in available continuous output power as ambient temperature increases is important when the converter is installed in warm vehicles, machinery spaces, cabinets or other enclosed areas.

⚠️ PRODUCT RATING NOTE: The product designation identifies this model as “360W”, while the supplied technical specifications list 430W continuous output at 25°C and 360W continuous output at 40°C. Both figures have been retained exactly as supplied.

⚠️ IMPORTANT: If exact output capability at a particular operating temperature is critical, confirm the current manufacturer datasheet for the exact model before final system design.

---

🔥 HIGH-TEMPERATURE PROTECTION

The Orion-Tr incorporates high-temperature protection.

When ambient temperature becomes high, the converter automatically reduces its output current to help protect the unit.

Available output capability can therefore be lower in hot operating environments.

⚠️ IMPORTANT: Provide sufficient clearance for heat dissipation and avoid mounting the converter near exhaust components, engines, heaters or other significant sources of heat.

---

🛡️ SHORT-CIRCUIT PROOF

The supplied product information states that Orion-Tr models are short-circuit proof.

This provides built-in protection against output short-circuit conditions within the converter's designed operating parameters.

⚠️ IMPORTANT: Internal short-circuit protection does not replace correctly selected external circuit protection for the supply wiring, output wiring and connected equipment.

---

🔗 PARALLEL MULTIPLE UNITS FOR MORE OUTPUT CURRENT

The supplied information states that compatible Orion-Tr converters can be connected in parallel to increase total available output current.

An unlimited number of compatible units can be connected in parallel according to the supplied product information.

This provides flexibility for higher-current systems where a single 30A converter does not provide sufficient output capacity.

⚠️ IMPORTANT: Parallel installations should follow the manufacturer's requirements, including correct output-voltage matching, cable sizing, circuit protection and load distribution.

---

📈 88% EFFICIENCY

Supplied efficiency:

88%

The converter's input power requirement will be greater than its usable output power because of normal conversion losses.

At high output loads, the 24V-side input current can therefore be substantial and should be considered when designing the source wiring and protection.

⚠️ IMPORTANT: Size input wiring and circuit protection according to the converter's actual input-current requirement, cable length and acceptable voltage drop rather than relying only on the 30A output-current rating.

---

⚡ UNDER-VOLTAGE SHUTDOWN & RESTART

Input voltage range:

20V–35V DC

Under-voltage shutdown:

14V

Under-voltage restart:

15V

The supplied specifications list an under-voltage shutdown threshold of 14V and restart threshold of 15V.

⚠️ SPECIFICATION NOTE: The supplied 14V shutdown and 15V restart thresholds are below the stated normal input-voltage range of 20V–35V. These values have been retained exactly as supplied. For an installation that depends on precise low-voltage behaviour, confirm the current manufacturer datasheet for this exact model.

---

🔋 NO-LOAD & DISABLED CURRENT CONSUMPTION

No-load input current:

<220mA

Current consumption when disabled via remote port:

<200µA

The no-load figure represents current consumed while the converter remains powered without supplying a significant output load.

When disabled via its remote port, current consumption reduces substantially.

---

🎛️ REMOTE PORT DISABLE FUNCTION

The supplied technical specifications state that current consumption falls below 200µA when the converter is disabled via its remote port.

This provides a low-consumption method of disabling the converter while leaving the main power wiring connected.

⚠️ IMPORTANT: Detailed remote-port wiring and control information is not included in the supplied specifications. Refer to the applicable manufacturer instructions before connecting the remote port.

---

🔊 LOW OUTPUT NOISE

Supplied output noise:

2mV RMS

The low supplied output-noise specification can be useful for compatible communications, control and electronic equipment requiring a stable regulated DC supply.

---

⛔ NOT INTENDED FOR BATTERY CHARGING

Although the Orion-Tr provides an adjustable output voltage, the supplied product information specifically states that this model is not intended for battery charging.

For battery-charging applications, the supplied information recommends considering an Orion-Tr Smart.

⚠️ IMPORTANT: Do not use the adjustable output as a substitute for a dedicated DC-DC battery charger. Battery charging requires appropriate control for the battery voltage, chemistry and charging requirements.

---

🛡️ IP43 PROTECTION

The Orion-Tr provides IP43 ingress protection when installed with the screw terminals oriented downwards.

Correct mounting orientation is therefore required to achieve the supplied IP43 rating.

⚠️ IMPORTANT: IP43 does not mean waterproof or suitable for immersion. Install the converter in an appropriately protected location.

---

🔩 SCREW-TERMINAL CONNECTIONS

The Orion-Tr uses screw terminals for its DC electrical connections.

The supplied product information states that no special tools are required for installation.

Maximum cable cross-section:

16mm² / AWG6

⚠️ IMPORTANT: 16mm² / AWG6 is the maximum cable size accepted by the terminals. Actual cable size should be selected according to current, cable length, allowable voltage drop and circuit-protection requirements.

---

⚡ INTERNAL INPUT FUSE

The supplied product information states that 12V and 24V input Orion-Tr models include an internal input fuse.

As this is a 24V-input model, the internal input fuse applies.

The supplied information states that the fuse is not replaceable.

⚠️ IMPORTANT: The internal fuse does not automatically eliminate the need for correctly positioned external fuse or circuit-breaker protection in the supply wiring.

---

🌡️ OPERATING CONDITIONS

Operating temperature range:

-20°C to +55°C

Maximum humidity:

95% non-condensing

Output current reduces at elevated ambient temperatures as part of the converter's thermal protection behaviour.

⚠️ IMPORTANT: Avoid condensation and install the converter within the supplied temperature and humidity limits.

---
