1.Remote Sense
※ The Remote Sense compensates voltage drop on the load wiring up to 0.5V
◎ The signal should be connected to the positive terminal of the load whereas signal to the negative terminal.+S -S
◎ This configuration is based on the assumption the Output Voltage Programming is not activated and power supply is ON.

3.DC_OK signal
"DC_OK" is an open collector signal. It indicates the output status of the power supply. It can operate in two ways : One is sinking current from external※
TTL signal ; the other is sending out a TTL voltage signal.
The maximum sink current is 10mA and the maximum external voltage is 5.6V.Sinking current from external TTL signal:◎
◎ Sending out TTL voltage signal :

1000W Power Supply with Single Output
RSP-1000 series
File Name:RSP-1000-SPEC 2018-01-15
※ Difference of output voltages among parallel units should be less than 0.2V.
RSP-1000 has the built-in active current sharing function and can be connected in parallel, up to 4 units, to provide higher output power as exhibited below :
※ The total output current must not exceed the value determined by the following equation:
※ ×When the total output current is less than 5% of the total rated current, or say (5% of Rated current per unit) (Number of unit)
the current shared among units may not be fully balanced.
Maximum output current at parallel operation=(Rated current per unit) (Number of unit) 0.9××
+S,-S and CS are connected mutually in parallel.◎
※The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
