Automatic Transfer Switch Control Modules
DSE334
Auto Transfer Switch Control Module
The DSE334 Automatic Transfer Switch Control Module monitors the voltage and frequency of an incoming AC supply from two different sources. These sources can be generator or mains (utility), or a combination of both.
The control module monitors Source 1 (S1) and Source 2(S2). When a failure occurs a start command is issued to the inactive source to take over the load. The module will return the load to the mains (utility) as soon as this becomes available.

Specification
DC SUPPLY
CONTINUOUS VOLTAGE RATING8 V to 35 V Continuous
CRANKING DROPOUTS
Able to survive 0 V for 50 mS, providing supply was at least 10 V before dropout and supply recovers to 5 V. This is achieved without the need for internal batteries. LEDs and backlight will not be maintained during cranking.
MAXIMUM OPERATING CURRENT
292 mA at 12 V, 167 mA at 24 V
MAXIMUM STANDBY CURRENT
101 mA at 12 V, 66 mA at 24 V
