🔌 STEP UP 12V DC TO 24V-CLASS POWER

The Orion-Tr is designed for systems where a nominal 12V DC supply is available but connected equipment requires a higher 24V-class DC voltage.

Input voltage range: 8V–17V DC

Nominal output voltage: 24.2V DC

Adjustable output range: 20V–30V DC

This allows compatible 24V equipment to be operated from an appropriate 12V source while maintaining galvanic isolation between the two circuits.

⚠️ IMPORTANT: Confirm the required input voltage of the connected equipment before setting the converter output. Incorrect output voltage can damage connected equipment.

---

🎛️ ADJUSTABLE 20–30V OUTPUT

Nominal output voltage: 24.2V

Output-voltage adjustment range: 20V–30V

Output-voltage tolerance: ±0.2V

The adjustable output makes the converter suitable for compatible electrical equipment requiring a specific regulated supply within the 20V to 30V range.

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

---

🛡️ GALVANICALLY ISOLATED INPUT & OUTPUT

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

Supplied galvanic-isolation rating:

200V DC between input, output and case

This electrically separates the input-side and output-side circuits rather than using a direct common electrical path.

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

⚠️ IMPORTANT: Confirm that the supplied 200V DC isolation rating is suitable for the requirements of your complete electrical system.

---

⚡ 5A CONTINUOUS OUTPUT

Continuous output current at nominal output voltage and 25°C:

5A

Maximum output current at nominal output voltage:

6.3A for 10 seconds

Short-circuit output current:

23A

The 5A rating should be used when calculating normal sustained output loads at the stated conditions.

⚠️ IMPORTANT: The 6.3A figure is a maximum 10-second output rating and should not be treated as a continuous-current specification.

⚠️ IMPORTANT: The 23A short-circuit current is a protection-related specification and is not an allowable equipment load.

---

🔋 120W CONTINUOUS OUTPUT AT 25°C

Continuous output power at 25°C:

120W

Continuous output power at 40°C:

110W

The reduction in rated continuous output as ambient temperature increases is important when designing installations in hot vehicles, machinery compartments or enclosed electrical cabinets.

⚠️ IMPORTANT: Do not assume the converter can continuously provide its 120W at 25°C rating when operating in a hotter environment.

---

🔥 HIGH-TEMPERATURE PROTECTION

The Orion-Tr incorporates high-temperature protection.

When ambient temperature increases, the converter reduces output current to help protect itself.

Actual available output may therefore be lower than the nominal specification in hot installation environments.

⚠️ IMPORTANT: Install the converter where heat can dissipate effectively and avoid mounting it next 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 placing a high-current switch directly in the main DC input cable.

The remote on/off can 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 extremely low disabled-current consumption can be useful in battery-powered vehicle and auxiliary systems 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:

7V

Under-voltage restart:

7.5V

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

This helps prevent continued converter operation when the input supply falls outside its intended operating range.

---

🛡️ 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 limits.

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

---

🔗 PARALLEL FOR MORE OUTPUT CURRENT

The supplied product 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 can provide additional current capacity where a single 5A converter is insufficient.

⚠️ IMPORTANT: Parallel installations must follow the manufacturer's requirements. Output-voltage matching, cable sizing, circuit protection and load sharing should all be considered.

---

📈 88% EFFICIENCY

Supplied efficiency:

88%

The converter's input-side power requirement will be higher than its output power because of normal conversion losses.

This is particularly important in step-up applications because input current from the 12V source can be substantially higher than the 24V-side output current.

⚠️ IMPORTANT: Size the 12V input wiring and source protection according to actual input-current requirements rather than assuming the 5A output-current figure also applies to the input side.

---

🔋 NO-LOAD CURRENT

No-load input current:

<80mA

This represents the current consumed when the converter remains powered but is not supplying a significant load.

When disabled through its remote port, supplied current consumption reduces to less than 200µA.

---

🔊 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 DC power supply.

---

⛔ NOT INTENDED FOR BATTERY CHARGING

The Orion-Tr provides an adjustable output voltage, but 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 a product and charging profile suitable for the battery chemistry, voltage and application.

---

🛡️ 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 of the screw terminals.

Maximum cable cross-section:

6mm² / AWG10

⚠️ IMPORTANT: 6mm² / AWG10 is the maximum cable size accepted by the terminals. Actual cable size must be selected according to current, cable length, voltage drop and circuit-protection requirements.

---

⚡ INTERNAL INPUT FUSE

The supplied information states that 12V and 24V input Orion-Tr models are fitted with an input fuse.

As this is a 12V-input model, the internal input fuse applies.

The fuse is specified as non-replaceable.

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

---

🌡️ OPERATING CONDITIONS

Operating temperature:

-20°C to +55°C

Maximum humidity:

95% non-condensing

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

⚠️ IMPORTANT: Avoid condensation and provide a suitable installation environment within the supplied temperature and humidity limits.

---

🚤 MARINE ELECTRICAL SYSTEMS

Galvanic isolation can make the Orion-Tr relevant to compatible marine systems where electrical separation between the source circuit and output circuit is required.

Suitability still depends on the complete system design, environmental exposure, required isolation level and connected electrical load.

---
