- Input Voltage: ±145 Vdc to ±200 Vdc
- Output Voltage: -54 Vdc
- Output Power: 1350W total (450W per individual port)
- Output Current: 9.4 A
- Connections: 1 input, 4 isolated outputs
- Dimensions: 203.2 x 457.2 x 109 mm (8 x 18 x 4.3 in)
- Weight: 9 kg (19.8 lb)
Features and Protection
The unit includes advanced monitoring and control capabilities for each of the four output channels, including power cycling, load shedding, and voltage/current readings. Protection features include:
- Safe start function
- Current limit and short circuit protection
- Reverse polarity protection
- Output high voltage shutdown
- Power limiting
- Over-temperature protection
Environmental Requirements

Practical help
Common problems
Input voltage out of range
Ensure the input voltage is within the specified range of ±145 Vdc to ±200 Vdc.
Over-temperature shutdown
Ensure the ambient temperature does not exceed 65°C. Note that full rated output is only guaranteed up to 55°C.
Output overload
Verify that the load on each individual port does not exceed 450W and the total load does not exceed 1350W.
Before use
- Verify input voltage is between ±145 Vdc and ±200 Vdc.
- Ensure cabling is 12 AWG (4 mm²) or 14 AWG (2.5 mm²) hybrid or copper only.
- Confirm the installation site is within the operating temperature range of -40°C to 65°C.
- Ensure the mounting surface supports the IP68 rated enclosure (pole, wall, underground, or aerial).
- Check that the Cordex CXC HP system controller is available for remote monitoring.
