DSE705 Auto Transfer Switch Control Module

DSE705 Auto Transfer Switch Control Module


Project Description

The DSE705 is an Automatic Transfer Switch Control Module for use with generator applications. The module monitors an incoming mains (utility) supply and issues a start command to the generator control system when the power fails.

When the generator is producing the required output the DSE705 switches the load from the mains (utility) supply. When the mains (utility) supply returns the DSE705 switches the load back. The generator is instructed to cool down and stop.

DC Supply OUTPUTS
CONTINUOUS VOLTAGE RATING
8 V to 35 V Continuous
START & RUN OUTPUTS
1.2 Amp DC at supply voltage. Switches to battery negative when active
CRANKING DROPOUTS
Able to survive 0V for 50mS, providing supply was at least 10V before dropout and supply recovers to 5V. This is achieved without the need for internal batteries.
CLOSE GEN/MAINS (UTILITY) CONTROL OUTPUTS
1.2 Amp DC at supply voltage. Switches to battery negative when active
MAXIMUM OPERATING CURRENT
50mA
AUXILIARY OUTPUTS
1.2 Amp DC at supply voltage. Switches to battery negative when active
MAXIMUM STANDBY CURRENT
50mA
ALTERNATOR INPUT RANGE
75V(L-N) to 333V AC (L-N) absolute maximum
ALTERNATOR INPUT FREQUENCY
50Hz – 60Hz at rated engine speed (Minimum: 75V AC L-N)
