🔌 CONVERT 24V DC TO 12.5V DC

The Orion-Tr converter is intended for installations where a nominal 24V supply is available but selected equipment requires approximately 12V DC.

Input voltage range:

18V–35V DC

Output voltage:

12.5V DC

This can make it suitable for compatible trucks, commercial vehicles, marine systems, machinery and other 24V electrical installations requiring a dedicated lower-voltage supply.

⚠️ IMPORTANT: Confirm that the connected equipment is designed to operate correctly from a 12.5V DC supply before installation.

---

⚡ 12A CONTINUOUS OUTPUT

The supplied technical specification lists:

Continuous output current: 12A

Maximum output current: 25A

The continuous 12A figure should be used when determining normal sustained load capability.

⚠️ IMPORTANT: The 25A figure is listed as maximum output current and should not automatically be treated as a continuous operating rating.

---

⚠️ 10A MODEL NAME VS 12A CONTINUOUS SPECIFICATION

The supplied product title identifies the unit as:

Orion-Tr 24V to 12V-10A (120W)

However, the supplied technical specification lists:

Continuous output current: 12A

Maximum output current: 25A

Both pieces of information have been preserved in this listing.

⚠️ IMPORTANT: If the exact continuous-current specification is critical to your application, confirm the current manufacturer datasheet for the exact model before system design or installation.

---

📈 HIGH-EFFICIENCY SYNCHRONOUS RECTIFICATION

The Orion-Tr uses synchronous rectification to provide efficient DC voltage conversion.

Supplied efficiency:

97%

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

High efficiency helps minimise wasted power and reduces unnecessary heat generation when the converter is operating under load.

---

🛡️ IP43 PROTECTION

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

Correct mounting orientation is therefore required to achieve the stated ingress-protection rating.

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

---

🔩 SCREW-TERMINAL CONNECTIONS

The Orion-Tr uses screw terminals for its DC electrical connections.

The supplied product information states that no special tools are required for connection to the screw terminals.

Maximum cable cross-section:

6mm² / AWG10

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

---

🔌 NON-ISOLATED DESIGN

Galvanic isolation:

No

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

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

---

🔋 LOW OFF-LOAD CURRENT

Supplied off-load current:

<45mA

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

For battery-powered systems that may remain unused for extended periods, standby consumption should be considered as part of the overall power-system design.

---

🌡️ OPERATING TEMPERATURE RANGE

Operating temperature:

-20°C to +55°C

The converter is designed to operate across this temperature range when correctly installed and operated within its electrical limits.

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

---

🚚 24V VEHICLE APPLICATIONS

The Orion-Tr can provide a practical solution in compatible trucks, buses, commercial vehicles and other nominal 24V vehicle systems where selected accessories require approximately 12V DC.

Potential compatible loads can include:

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

⚠️ IMPORTANT: Add together the current consumption of all connected accessories and ensure the sustained load remains within the supplied continuous-current specification.

---

🚤 MARINE & MOBILE ELECTRICAL SYSTEMS

The converter may also suit compatible marine and mobile electrical installations where a nominal 24V supply needs to power selected 12V equipment.

The installation must still comply with the converter’s voltage range, current limits, mounting orientation and IP43 environmental requirements.

---

🏗️ INDUSTRIAL & CONTROL APPLICATIONS

The broad 18–35V input range and compact construction can make the Orion-Tr suitable for compatible machinery, control equipment and industrial DC systems requiring a regulated 12.5V output from a nominal 24V source.

Confirm current demand, required isolation, environmental conditions and operating voltage before installation.

---

🔋 NOT A DEDICATED BATTERY CHARGER

The supplied information identifies this product as a DC-DC converter with a 12.5V output.

It is not described as a multi-stage 12V battery charger.

⚠️ IMPORTANT: Do not use this converter as a substitute for a dedicated battery charger unless the battery manufacturer and complete system design specifically allow operation from a fixed 12.5V supply.

---

📏 COMPACT DIMENSIONS

Height: 73mm

Width: 94mm

Depth: 37mm

Weight: Approximately 0.2kg

The compact enclosure makes the unit practical for installation into suitably protected electrical panels, cabinets and equipment spaces.
