## Overview

The DSE335 Original, proudly made in the UK, is a cutting-edge automatic transfer switch control module that monitors voltage and frequency from two AC sources—generator and mains. It intelligently switches power to maintain continuous supply, survives brief voltage dropouts without batteries, and offers flexible configuration options, making it the go-to solution for professionals demanding reliable, seamless power management.

## Description

The DSE335 MKII is an automatic transfer switch controller designed to monitor the voltage and frequency of incoming AC supplies from two different sources. These are either generator or mains (utility), or a combination of both. The module monitors S1 (source 1) and in the event of a failure issues a start command to S2 (source 2). Various timing sequences are available to prevent nuisance starting on minor supply breaks. The module is configured using the DSE Configuration Suite PC Software. Selected front panel editing is also available. Configurable inputs and outputs make the DSE335 MKII fully flexible to suit a wide variety of applications.

## Features

- DSE0335-11 Original - Made in UK
- DSE335-11 Automatic Transfer Switch Control Module has been expertly developed to monitor 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.
- 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.
- 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.
- MAXIMUM OPERATING CURRENT: 480 mA at 12 V, 360 mA at 24 V. MAXIMUM STANDBY CURRENT: 126 mA at 12 V, 96 mA at 24 V
- S1 VOLTAGE RANGE: 15 V AC to 415 V AC (L-N) FREQUENCY RANGE: 3.5 Hz to 75 Hz
- OUTPUTS OUTPUTS A & E: Normally closed ­­­volt-free output 8 A AC at 250 V AC. OUTPUTS B & F: Normally open volt-free output 8 A AC at 250 V AC
