Type S Power Supply is field selectable for 48 or 125 Vdc. Selection
must be implemented at time of installation. This Power Supply option
is factory set for 125 Vdc.
Isolation
1500 Vac at 60 hertz for one minute in accordance with IEC 255-5 and
ANSI/IEEE C37.90-1989 (Dielectric Test).
Radio Frequency
Field Tested using a five watt, hand-held transceiver operating at
Interference (RFI)
random frequencies centered around 144 MHz and 440 MHz, with the
antenna located six inches from the relay in both horizontal and vertical
planes.
Surge Withstand Capability
Qualified to ANSI/IEEE C37.90.1-1989
Standard Surge Withstand Capabil-
ity (SWC) Tests for Protective Relays and Relay Systems.
UL Recognized
UL Recognized per Standard 508, UL File No. E97033. Note: Relay is not
UL Recognized for output contact voltages greater than 250 volts and input
power supply voltages greater than 150 volts.
