🔌 CONVERT 24V DC TO 12.5V DC

The Orion-Tr converter is designed for electrical systems where a nominal 24V supply is available but selected accessories or equipment require approximately 12V DC.

Input voltage range:

18V–35V DC

Output voltage:

12.5V DC

This makes the converter suitable for compatible trucks, buses, commercial vehicles, marine systems, machinery and other 24V installations requiring a regulated lower-voltage power supply.

⚠️ IMPORTANT: Confirm that the connected appliance or accessory is suitable for operation from a 12.5V DC supply before installation.

---

⚡ 15A CONTINUOUS OUTPUT

The Orion-Tr provides a supplied continuous output-current rating of 15A.

Continuous output current:

15A

Maximum output current:

20A

The 15A continuous rating should be used when calculating normal sustained accessory loads.

⚠️ IMPORTANT: The 20A specification is listed as maximum output current and should not be treated as the normal continuous operating rating.

---

🔋 180W PRODUCT RATING

The product is designated as the Orion-Tr 24V to 12V-15A (180W) DC-DC Converter.

The supplied technical specifications separately list a 12.5V output and 15A continuous output-current capability.

For system design, use the manufacturer's stated voltage, continuous-current and maximum-current limits rather than relying on wattage alone.

---

📈 HIGH-EFFICIENCY SYNCHRONOUS RECTIFICATION

The Orion-Tr uses synchronous rectification to achieve high conversion efficiency.

Supplied efficiency:

97%

The supplied product information also states that full-load efficiency exceeds 95%.

Higher efficiency reduces wasted electrical energy and unnecessary heat generation, which is particularly useful in battery-powered vehicle and auxiliary electrical systems.

---

🛡️ IP43 PROTECTION

The converter provides IP43 ingress protection when installed with the screw terminals oriented downwards.

Correct mounting orientation is therefore important to achieving the stated IP rating.

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

---

🔩 EASY SCREW-TERMINAL CONNECTION

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: Cable size must still be selected according to circuit current, cable length, voltage drop, installation temperature and circuit-protection requirements.

---

🔌 NON-ISOLATED DESIGN

Galvanic isolation:

No

The input and output circuits of this converter are therefore not galvanically isolated from each other.

⚠️ IMPORTANT: If your installation requires electrical isolation between the 24V input circuit and the 12V output circuit, this non-isolated Orion-Tr model is not suitable.

---

🔋 LOW OFF-LOAD CURRENT

Supplied off-load current:

<35mA

This represents the converter's current consumption while powered but not supplying a significant connected load.

For battery-powered systems left unused for extended periods, this standby consumption should be considered as part of the overall electrical-system design.

---

🌡️ OPERATING TEMPERATURE RANGE

Supplied operating temperature:

-20°C to +55°C

The Orion-Tr is designed to operate across this temperature range when installed and operated within its electrical specifications.

⚠️ IMPORTANT: Avoid mounting the converter close to engines, exhaust systems, heaters or other sources of excessive heat.

---

🚚 24V TRUCK & COMMERCIAL VEHICLE APPLICATIONS

The Orion-Tr can provide a practical solution in compatible trucks, buses and commercial vehicles that use a nominal 24V electrical system but require power for selected 12V equipment.

Potential compatible loads can include:

• 💡 12V lighting
• 📡 Communications equipment
• 📱 Electronics and charging accessories
• 🎛️ Control equipment
• 🔌 Selected 12V vehicle accessories
• 🧰 Compatible auxiliary equipment

⚠️ IMPORTANT: Add together the continuous current requirements of all connected accessories and ensure the total remains within the converter's 15A continuous output rating.

---

🚤 MARINE & MOBILE ELECTRICAL SYSTEMS

The Orion-Tr may also suit compatible marine and mobile electrical systems where a nominal 24V supply needs to operate selected 12V equipment.

The complete installation must remain within the converter's input-voltage range, output-current limits, temperature range and environmental protection requirements.

---

🏗️ INDUSTRIAL & CONTROL APPLICATIONS

The broad 18–35V input range and regulated 12.5V output can make the converter useful in compatible industrial equipment, machinery and control systems operating from nominal 24V DC supplies.

Confirm connected-load current, required isolation, installation environment and cable requirements before installation.

---

💡 MULTIPLE 12V ACCESSORIES

The 15A continuous output provides greater accessory capacity than smaller Orion-Tr converters and can support multiple compatible 12V loads from a single converter.

For example, several low-current accessories may be connected where their combined continuous current remains within the 15A rating.

⚠️ IMPORTANT: Always calculate combined current demand rather than relying on the number of accessories connected.

---

🧊 COMPATIBLE 12V REFRIGERATION

The converter may be capable of powering compatible 12V refrigeration equipment where both running current and compressor startup demand remain within the converter's specifications.

⚠️ IMPORTANT: Compressor fridges can draw substantially more current during startup than during normal operation. Check the appliance manufacturer's maximum current or startup-current specification before connection.

---

🔋 NOT A DEDICATED BATTERY CHARGER

The supplied information identifies the Orion-Tr as a DC-DC voltage converter with a regulated 12.5V output.

It is not described as a multi-stage battery charger.

⚠️ IMPORTANT: Do not automatically use this converter to charge a 12V lead-acid or lithium battery. Where battery charging is required, use an appropriate charger with the correct charging profile for the battery chemistry.

---

📏 COMPACT DIMENSIONS

Height: 73mm

Width: 94mm

Depth: 45mm

Weight: Approximately 0.25kg
