⚠️ IMPORTANT: Parallel installation should follow the manufacturer's requirements, including correct output-voltage matching, cable sizing, circuit protection and load distribution.

---

📈 89% EFFICIENCY

Supplied efficiency:

89%

This Orion-Tr is a substantial step-up converter, raising a nominal 12V supply to approximately 48V.

Because voltage is increased significantly, input current on the 12V side can be considerably higher than the current delivered on the 48V output side.

Normal conversion losses also mean the input source must provide more electrical power than is ultimately delivered to the connected load.

⚠️ IMPORTANT: Do not size the 12V input cable, fuse or source capacity based on the 8A output-current figure. Input current must be determined from actual load power, input voltage, efficiency, cable length and allowable voltage drop.

---

⚡ HIGH-POWER 12V INPUT REQUIREMENTS

Producing hundreds of watts at approximately 48V from a nominal 12V source places substantial demand on the input electrical system.

The 12V source, cabling, terminals and protection system must all be capable of supporting the converter's required input current without excessive voltage drop.

This is particularly important at high output load and when the input voltage is toward the lower end of the supplied operating range.

⚠️ IMPORTANT: A converter of this power level should be treated as a high-current 12V load when designing the input wiring.

---

⚡ UNDER-VOLTAGE SHUTDOWN & RESTART

Input voltage range:

10V–17V DC

Under-voltage shutdown:

7V

Under-voltage restart:
