Water cooled power supply with three 6kW modules TRC – R 18.0kW

Frontview without lid (150V DC version)
Terepcos TRC – R 18.0kW 19” rack water cooled power supply is a spinoff of the TRC – 3.0kW power supply family, which has the identical high-speed voltage and current loop control.
Because of the water cooled components it is possible to design a compact 18kW power supply which fits into 3HE 19“ rack with a depth of 495mm. In the full-blown version, the rack is equipped with three 6kW power supplies in share mode which results in a total power of 18kW or three different DC output voltages with a power of 6kW each. The different output voltages (150V, 250V and 400V) can be selected by insertion options.
Further the 6kW power block can be cascaded so that a 12kW and a 18kW power supply can be configured.
Based on the modularity of the system it allows a high flexibility to supply a wide range of applications such as LED driving, inductive heating, or other industrial solutions. This power supply could also drive your application. Because of the sealed system it is not possible that polluted air or dust can enter the power supply housing.
The power supply was developed by Terepco GmbH in Germany which is active in power supply design, production and repair.
The TRC – R 18.0kW 19″ Rack power supply has different output voltages (150V, 250V and 400V) which can be selected by insertion options.
- Output voltage: 20-150V DC 0-120A
- Output voltage: 125-250V DC 0-72A
- Output voltage: 200-400V DC 0-45A
Other output voltages between 150V and 400V can be provided if requested.
