🔌 STEP UP 24V DC TO 48V-CLASS POWER

The Orion-Tr is designed for electrical systems where a nominal 24V DC source must operate equipment requiring a higher 48V-class DC supply.

Input voltage range: 16V–35V DC

Nominal output voltage: 48.2V DC

Adjustable output range: 40V–60V DC

This allows compatible higher-voltage equipment to operate from an appropriate 24V source while maintaining galvanic isolation between the input and output circuits.

⚠️ IMPORTANT: Confirm the exact voltage requirement of connected equipment before setting the converter output. Incorrect output voltage can damage connected electrical equipment.

---

🎛️ ADJUSTABLE 40–60V OUTPUT

Nominal output voltage: 48.2V DC

Output-voltage adjustment range: 40V–60V DC

Output-voltage tolerance: ±0.2V

The adjustable output allows the converter to be configured for compatible electrical equipment requiring a specific DC supply within this range.

⚠️ IMPORTANT: Measure and verify 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 24V input-side circuit from the higher-voltage output-side circuit rather than sharing a direct common electrical path.

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

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

---

⚡ 6A CONTINUOUS OUTPUT AT 40°C

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

6A

Maximum output current at nominal output voltage:

8A for 10 seconds

Short-circuit output current:

25A

The 6A continuous-current specification should be used when determining sustained output loads at the stated 40°C condition.

⚠️ IMPORTANT: The 8A figure applies for a maximum of 10 seconds and must not be treated as a continuous-current rating.

⚠️ IMPORTANT: The 25A short-circuit current is a protection-related specification and is not an allowable appliance-load rating.

---

🔋 OUTPUT POWER & TEMPERATURE

Continuous output power at 25°C:

320W

Continuous output power at 40°C:

280W

The supplied specification also states that the converter should be derated by 3% per °C above 40°C.

This means available output power continues to reduce as ambient temperature rises above 40°C.

⚠️ PRODUCT RATING NOTE: The product designation includes “280W”, while the supplied technical specification lists 320W continuous output at 25°C and 280W continuous output at 40°C. Both figures have been retained exactly as supplied.

---

🌡️ 3% PER °C DERATING ABOVE 40°C

The supplied operating information specifies:

Operating range: -20°C to +55°C

Derating above 40°C: 3% per °C

This thermal derating is important when the converter is installed in a warm vehicle compartment, electrical enclosure, machinery space or other location where ambient temperature may regularly exceed 40°C.

⚠️ IMPORTANT: Do not design an installation around the 25°C output-power figure if the converter will normally operate at significantly higher ambient temperatures.

---

🔥 HIGH-TEMPERATURE PROTECTION

The Orion-Tr incorporates high-temperature protection.

At elevated ambient temperatures, output current automatically reduces to help protect the converter.

This means available output can be lower than the nominal specification in hot operating environments.

⚠️ IMPORTANT: Provide appropriate space for heat dissipation and avoid mounting the converter adjacent to exhaust components, engines, heaters or other major heat sources.

---

🎛️ REMOTE ON/OFF TERMINAL

The Orion-Tr includes a remote on/off terminal.

This allows the converter to be switched without installing a high-current switch directly into the main input wiring.

The remote on/off may be controlled using a suitable low-power switch or, where appropriate, a compatible engine run/stop signal.

Current consumption when disabled via the remote port:

<200µA

This very low disabled-current consumption can be useful in battery-powered installations where the converter may remain switched off for extended periods.

⚠️ IMPORTANT: Follow the applicable manufacturer wiring instructions when connecting the remote on/off terminal or integrating it with an engine run/stop circuit.

---

⚡ UNDER-VOLTAGE SHUTDOWN & RESTART

Under-voltage shutdown:

14V

Under-voltage restart:

15V

The converter is designed to stop operating when input voltage falls below the supplied shutdown threshold and restart once sufficient input voltage returns.

---

🛡️ 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 limits.

⚠️ IMPORTANT: Internal short-circuit protection does not replace correctly sized external fuses or circuit breakers required to protect the installation wiring and connected equipment.

---

🔗 PARALLEL UNITS FOR MORE OUTPUT CURRENT

The supplied product information states that compatible Orion-Tr converters may 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 flexibility for applications requiring more total current than a single 6A converter can provide.

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

---

📈 89% EFFICIENCY

Supplied efficiency:

89%

Because this is a step-up converter, input current on the 24V side can be substantially higher than the 6A output-current figure would suggest.

Normal conversion losses also mean input power will be higher than useful output power.

⚠️ IMPORTANT: Do not size the 24V input wiring or circuit protection based only on the 6A output-current rating. Calculate actual input current from output power, input voltage and converter efficiency.

---

🔋 NO-LOAD & DISABLED CURRENT CONSUMPTION

No-load input current:

<120mA

Current consumption when disabled via remote port:

<200µA

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

Using the remote port to disable the unit reduces its current consumption significantly.

---

🔊 LOW OUTPUT NOISE

Supplied output noise:

2mV RMS

The low supplied output-noise figure 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 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 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 stated 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 must be selected according to circuit current, cable length, voltage drop and fuse or circuit-breaker requirements.

---

⚡ INTERNAL INPUT FUSE

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

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

The supplied information states that the input fuse is not replaceable.

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

---

🌡️ OPERATING CONDITIONS

Operating temperature range: -20°C to +55°C

Thermal derating: 3% per °C above 40°C

Maximum humidity: 95% non-condensing

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