Deep Sea Electronics DSE331 Auto Transfer Switch Control Module

The DSE331 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.

PRODUCT VARIANTS
0331-01 – 331 Auto Transfer Switch Control Module – 12/24 Volt DC Supply

DC SUPPLY

CONTINUOUS VOLTAGE RATING
8 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
168 mA at 12 V, 80 mA at 24 V

MAXIMUM STANDBY CURRENT
39 mA at 12 V, 20 mA at 24 V

OUTPUTS

OUTPUT A & B
Normally open volt-free output
8 A DC at 35 V DC

OUTPUT C & D
Changeover volt-free output
8 A DC at 35 V DC

AUXILLARY OUTPUT E, F, G & H
2 A DC at supply voltage
S1 & S2

VOLTAGE RANGE
15 V to 333 V AC (L-N)

FREQUENCY RANGE
3.5 Hz to 75 Hz
