The tables below describe DIP switch settings 1 through 4 of the 5.25 Amp Power Supply. For UL compliance,
DIP switches should be set to the defaults, as shown.
SW1&2 together define the Battery Load Test (also known as Battery Impedance Test)
Switch 1
Switch 2
Description
Off (DEFAULT)
Off (DEFAULT)
Recommended for standard operation. Load test
the battery every 59 minutes. Measured voltage
drop > 900mV fails the test.
Off
