🛡️ GALVANICALLY ISOLATED 12V POWER

The Orion-Tr provides galvanic isolation between its input, output and case.

Supplied galvanic isolation:

200V DC between input, output and case

This electrically separates the source-side circuit from the output-side circuit rather than using a direct common electrical path.

This can be useful in compatible vehicle, marine, communications and industrial systems where circuit separation or independent electrical referencing is required.

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

---

🔌 8–17V DC INPUT RANGE

Input voltage range:

8V–17V DC

Under-voltage shutdown:

7V

Under-voltage restart:

7.5V

The converter is designed to shut down if input voltage falls below the supplied threshold and restart once sufficient input voltage returns.

---

🎛️ 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 regulated supply within the 10V to 15V range.

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

---

⚡ 18A CONTINUOUS OUTPUT AT 40°C

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

18A

Maximum output current at nominal output voltage:

25A for 10 seconds

Short-circuit output current:

40A

The supplied 18A continuous-current specification should be used when calculating normal sustained loads under the stated conditions.

⚠️ IMPORTANT: The 25A figure applies for a maximum of 10 seconds and must not be treated as a continuous-current rating.

⚠️ IMPORTANT: The 40A short-circuit output-current figure is a protection-related specification and is not an allowable appliance-load rating.

---

🔋 OUTPUT POWER & TEMPERATURE

Continuous output power at 25°C:

280W

Continuous output power at 40°C:

220W

The substantial reduction in available continuous output power as ambient temperature increases is important when designing installations in warm vehicles, electrical cabinets, machinery compartments and other enclosed spaces.

⚠️ PRODUCT RATING NOTE: The product designation identifies this model as “220W”, while the supplied technical specifications list 280W continuous output at 25°C and 220W continuous output at 40°C. Both figures have been retained exactly as supplied.

⚠️ IMPORTANT: If exact power 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.

As ambient temperature rises, the converter automatically reduces output current to help protect itself.

This means available output capability can be lower in hot operating environments.

⚠️ IMPORTANT: Provide adequate clearance for heat dissipation and avoid mounting the converter adjacent to exhaust components, engines, heaters or other significant heat sources.

---

🛡️ SHORT-CIRCUIT PROOF

The supplied product information states that the 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 input 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 information.

This provides system-design flexibility where a single 18A converter does not provide sufficient total output capability.

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

---

📈 87% EFFICIENCY

Supplied efficiency:

87%

Conversion efficiency should be considered when sizing the input-side electrical system because the converter will draw more input power than it delivers as usable output power.

At higher output loads, input current can therefore be substantial even though input and output are both nominally 12V-class systems.

⚠️ IMPORTANT: Size the input wiring and circuit protection according to actual converter input current, cable length and voltage drop rather than relying only on the 18A output-current specification.

---

🔋 NO-LOAD & DISABLED CURRENT CONSUMPTION

No-load input current:

<80mA

Current consumption when disabled via remote port:

<200µA

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

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

---

🎛️ REMOTE PORT DISABLE FUNCTION

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

This provides a low-consumption method of switching the converter off while leaving the main DC wiring connected.

⚠️ IMPORTANT: The supplied information does not provide detailed remote-port wiring instructions. Refer to the applicable manufacturer manual before connecting or controlling the remote port.

---

🔊 LOW OUTPUT NOISE

Supplied output noise:

2mV RMS

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

---

⛔ NOT INTENDED FOR BATTERY CHARGING

Although the Orion-Tr provides an adjustable output, 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 battery charger. Battery charging requires appropriate control for 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 converter 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 12V-input model, the internal input fuse applies.

The supplied information states that this fuse is not replaceable.

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

---

🌡️ OPERATING CONDITIONS

Operating temperature range:

-20°C to +55°C

Maximum humidity:

95% non-condensing

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

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