SPECIFICATION RATING/DESCRIPTION CONDITION Equalize mode can be selected either with a Circuit Type Forward converter front panel push button, or a remote contact Switching Frequency ~ 150KHz closure. This sets the voltage to the equalize Temperature Range 0-50°C Operating level (adjustable). A timer is activated that -40 to +75°C Storage will reset back to float mode after a period of Humidity 95% RH Non-condensing time (0.1 to 99.9 hrs) that can be set from the Isolation 500V d-c, 100MΩ Output-case front panel with a thumbwheel selector.
