◎ The +S signal should be connected to the positive terminal of the load whereas -S signal to the negative terminal.
1. Voltage Drop Compensation
Sense lines should be twisted in pairs to minimize noise pick-up.

4. Remote ON-OFF Control
5. Alarm Signal Output
※ The power supply can be turned ON/OFF individually or along with other units by using the "Remote ON-OFF" function.
※ There are 2 alarm signals, DC OK and T-ALARM, in TTL signal form, on CN1. These signals are isolated from output. The maximum sink current
is 10mA.

6.Current Sharing with Remote Sense
RSP-1600 has the built-in active current sharing function and can be connected in parallel, up to 6 units, to provide higher output power as exhibited below :
※ The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
※ Difference of output voltages among parallel units should be less than 0.2V.
※ The total output current must not exceed the value determined by the following equation:
the current shared among units may not be balanced.
※ ×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)
※ Under parallel operation ripple of the output voltage may be higher than the SPEC at light load condition. It will go back to normal ripple level once the
output load is more than 5%.
※ CN500/SW1 Function pin connection
◎ -V(signal)DA,DB and are connected mutually in parallel.
◎ For Remote Sense / Local Sense, please refer to “Voltage Drop Compensation” section.
