🛡️ GALVANICALLY ISOLATED DC-DC CONVERSION

One of the key features of this Orion-Tr model is galvanic isolation between the input, output and case.

Supplied galvanic isolation:

200V DC between input, output and case

Galvanic isolation electrically separates the input-side circuit from the output-side circuit rather than sharing a common direct electrical path.

This can be important in compatible vehicle, marine, communications and industrial systems where electrical separation, ground-loop management or independently referenced circuits are required.

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

---

🔌 8–17V DC INPUT RANGE

Input voltage range:

8V–17V DC

This allows the converter to operate from compatible nominal 12V electrical systems where supply voltage varies during normal operation.

Under-voltage shutdown: 7V

Under-voltage restart: 7.5V

The converter is designed to shut down when the input voltage becomes too low and automatically restart once sufficient voltage is restored.

---

🎛️ 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 allows the converter to be configured for compatible electrical equipment requiring a specific regulated voltage within this range.

⚠️ IMPORTANT: Verify the required input voltage of the connected equipment and correctly set the converter output before connection.

---

⛔ NOT INTENDED FOR BATTERY CHARGING

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

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

⚠️ IMPORTANT: Do not use this converter as a substitute for a dedicated battery charger. Battery charging requires appropriate voltage control, charging stages and chemistry compatibility.

---

⚡ 9A CONTINUOUS OUTPUT

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

9A

Maximum output current:

12.5A for 10 seconds

Short-circuit output current:

32A

The 9A specification should be used when calculating normal sustained current requirements under the stated conditions.

⚠️ IMPORTANT: The 12.5A figure is a 10-second maximum output rating and should not be treated as a continuous operating specification.

⚠️ IMPORTANT: The 32A short-circuit current is a protection-related specification, not an allowable appliance load.

---

🔋 OUTPUT POWER & TEMPERATURE

Continuous output power at 25°C:

110W

Continuous output power at 40°C:

85W

The reduction in available continuous output power as ambient temperature rises is important when designing installations expected to operate in warm environments.

⚠️ IMPORTANT: Do not assume the converter can continuously provide its 110W 25°C rating at higher ambient temperatures.

---

🔥 HIGH-TEMPERATURE PROTECTION

The Orion-Tr includes high-temperature protection.

At elevated ambient temperature, the converter reduces output current to protect itself.

This means actual available output can be lower than the nominal rating when the converter is operating in a hot enclosure or near other heat-producing equipment.

⚠️ IMPORTANT: Install the converter where heat can dissipate appropriately. Avoid mounting it close to exhaust components, heaters or other significant heat sources.

---

🛡️ SHORT-CIRCUIT PROOF

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

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

⚠️ IMPORTANT: Short-circuit protection inside the converter does not replace correctly sized external circuit protection for the input wiring, output wiring or connected equipment.

---

🔗 UNLIMITED PARALLEL CONNECTION

The supplied product information states that an unlimited number of compatible Orion-Tr units can be connected in parallel to increase available output current.

Parallel installation can therefore provide greater total current capability where a single 9A converter is insufficient.

⚠️ IMPORTANT: Parallel converters must be installed according to the manufacturer's requirements, with appropriate cable sizing, circuit protection and voltage adjustment.

---

📈 87% EFFICIENCY

Supplied efficiency:

87%

Efficiency determines how much input power is converted into useful output power, with the remainder primarily becoming heat.

The converter's input-side current will therefore be higher than the output-side current would suggest when accounting for conversion losses.

---

🔋 LOW NO-LOAD CURRENT

No-load input current:

<50mA

This represents input current consumed while the converter remains powered without a significant output load.

Current consumption when disabled via its remote port:

<200µA

This very low disabled consumption can be useful in battery-powered applications where the converter is switched off for extended periods.

---

⚡ REMOTE PORT DISABLE FUNCTION

The supplied specifications state that the converter consumes less than 200µA when disabled via its remote port.

This indicates provision for remotely disabling the converter while maintaining extremely low current consumption.

⚠️ IMPORTANT: The supplied information does not provide the detailed wiring arrangement or operating logic for the remote port. Refer to the applicable manufacturer instructions before connection.

---

🛡️ 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

The large terminal capacity provides flexibility when selecting suitable cable for higher-current or longer cable-run installations.

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

---

⚡ INTERNAL INPUT FUSE

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

For this 12V-input model, the internal input fuse is therefore applicable.

The fuse is specified as non-replaceable.

⚠️ IMPORTANT: The internal fuse does not eliminate the need for appropriately positioned external circuit protection in the supply wiring where required by the installation.

---

🔊 VERY LOW OUTPUT NOISE

Supplied output noise:

2mV RMS

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

---

🌡️ OPERATING CONDITIONS

Operating temperature:

-20°C to +55°C

Maximum humidity:

95% non-condensing

⚠️ IMPORTANT: Avoid condensation and ensure the converter is installed within the supplied temperature and humidity limits.

---

🚙 VEHICLE AUXILIARY APPLICATIONS

• 🔌 Electrically isolated accessory circuits

⚠️ IMPORTANT: Confirm both voltage and current requirements of connected equipment before installation.

---

🚤 MARINE APPLICATIONS

Galvanic isolation can make the Orion-Tr particularly relevant to compatible marine and vessel electrical systems where separation between DC circuits is required.

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

---

📡 COMMUNICATIONS & ELECTRONICS

The combination of galvanic isolation, adjustable regulated output and supplied 2mV RMS output-noise specification can make the converter useful for compatible communications and electronic equipment.

Always confirm the device's required supply voltage, current consumption and permitted electrical noise before use.

---
