File Name:CSP-3000-SPEC 2021-09-03
3000W Power Supply with Single Output
CSP-3000 serie s
CSP-3000 has the built-in active current sharing function and can be connected in parallel, up to 3 units, to provide higher output power as exhibited below :
※ Difference of output voltages among parallel units should be less than 0.2V(Can Fine tune by SVR1).
※ The total output current must not exceed the value determined by the following equation:
Maximum output current at parallel operation=(Rated current per unit)×(Number of unit)×0.9
※ The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
※ When out current<( 50% rate current)×(Number of unit),
the current shared among units may not be fully balanced.
◎ CS+/CS- on CN1 are connected mutually in parallel(Note:CS+/CS- do not reverse connection).
◎ Under parallel operation, the "PV/PC" function is not available.
