3.6 REMOTE TURN ON TURN OFF
When power is ON at the source, the output may be turned ON or OFF with the remote control feature.
The remote ON/OFF RC (Remote Control) terminals can be controlled by a logic level (2.4V to 24V
"high" and 0.0 to 0.4V "low"), or a contact closure. When the RC terminals (on the front panel) are short
circuited by using either a mechanical switch or a low level logic signal, the RCW 350W output is cut
OFF. At low level logic, the maximum source current is 1.6mA. With the RC terminals open the RCW
350W output returns to within specifications. The RC terminals should remain open if not used (see Fig-
ure 6).
The RC terminals are isolated from the AC input and DC output terminals.
3.7 PARALLEL OPERATON
Identical RCW 350W Power Supplies can be connected in parallel. The output current of each Power
Supply can be balanced by connecting together all the CB terminals, connecting together all the (-) S
terminals and connecting together all the +S terminals of up to four RCW 350W Power Supply units
(see Figure 8). The current tolerance with up to four RCW 350W units in parallel should be within (±)
10% of the rated output current. With four RCW 350W units in parallel, the output voltage of any Power
Supply individually must be within 2% of the other power supply output voltages. The output current
range is 20 to 90% of the nominal output current.
