🔌 CONVERT 24V DC TO 12.7V DC

The Orion-Tr converter is designed for electrical systems where a nominal 24V supply is available but compatible equipment requires approximately 12V DC.

Input voltage range:

18V–35V DC

Output voltage:

12.7V DC

This makes the converter suitable for compatible 24V vehicle and auxiliary electrical systems requiring a regulated lower-voltage supply for selected 12V accessories.

⚠️ IMPORTANT: Confirm that the connected appliance or accessory is suitable for a 12.7V DC supply before installation.

---

⚡ 5A CONTINUOUS OUTPUT

The converter provides a continuous output-current rating of 5A.

At the stated 12.7V output voltage, this provides approximately 63.5W based on voltage × current, while the product is identified as a 60W converter.

Maximum output current is rated at 7A.

⚠️ IMPORTANT: Size connected loads according to the continuous 5A rating for normal operation. The 7A maximum figure should not automatically be treated as a continuous operating rating.

---

📈 HIGH-EFFICIENCY SYNCHRONOUS RECTIFICATION

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

Supplied efficiency:

95%

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

Higher conversion efficiency helps reduce wasted electrical energy and heat compared with less efficient conversion methods.

---

🛡️ 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 protection rating.

⚠️ IMPORTANT: The IP43 rating applies when the unit is installed with the screw terminals facing downwards. IP43 does not mean waterproof or suitable for immersion.

---

🔩 EASY SCREW-TERMINAL CONNECTION

The converter uses screw terminals for its DC connections.

This allows straightforward installation without specialised proprietary connectors or dedicated crimping tools for the converter terminals themselves.

Maximum cable cross-section:

3.3mm² / AWG12

⚠️ IMPORTANT: Cable size must still be selected according to current, cable length, voltage drop and installation conditions. Do not exceed the converter’s maximum terminal cable size.

---

🔌 NON-ISOLATED DESIGN

Galvanic isolation:

No

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

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

---

🔋 LOW OFF-LOAD CURRENT

Supplied off-load current:

<20mA

This is the current consumed by the converter when powered but not supplying a significant connected load.

For installations that may remain unused for extended periods, the effect of standby consumption should be considered as part of the overall battery-management strategy.

---

🌡️ OPERATING TEMPERATURE RANGE

Operating temperature:

-20°C to +55°C

The converter is designed to operate across a broad range of ambient temperatures when installed within its specified limits.

⚠️ IMPORTANT: Installation location, airflow, connected load and surrounding heat sources can affect operating temperature. Keep the converter away from excessive heat and install it in accordance with the manufacturer’s requirements.

---

🚚 SUITABLE FOR COMPATIBLE 24V VEHICLE SYSTEMS

The Orion-Tr can provide a practical voltage-conversion solution in compatible 24V vehicles where selected accessories require approximately 12V DC.

Potential applications can include compatible:

• 💡 12V lighting

• 📱 Low-current electronics
• 🎛️ Control equipment
• 🔌 Selected 12V accessories

⚠️ IMPORTANT: Total connected current must remain within the converter’s output limits.

---

🚤 MARINE & MOBILE ELECTRICAL SYSTEMS

The compact design may also suit compatible mobile or marine electrical systems using a nominal 24V DC supply and requiring a lower-voltage 12.7V output.

Installation must still respect the converter’s IP43 rating, mounting orientation, electrical limits and environmental requirements.

---

🏗️ INDUSTRIAL & EQUIPMENT APPLICATIONS

The broad 18–35V input range and compact form factor can make the converter useful for compatible machinery, control equipment and industrial DC systems where a regulated 12.7V supply is required from a nominal 24V source.

Confirm the connected load, required isolation, operating environment and voltage requirements before use.

---

📏 COMPACT DIMENSIONS

Height: 53mm

Width: 51mm

Depth: 27mm

Weight: Approximately 0.09kg

The small enclosure allows the converter to be integrated into compact electrical panels and equipment spaces where larger converters may be difficult to install.
