The LSL Products PRO-VCS Programmable Voltage Controlled Switch consists of one or two voltage controlled switches driving a pair of power relays, packaged inside a small, epoxy encapsulated enclosure. Each switch/relay combination (or channel) is independently programmable for turn on and turn off input voltages over a range of either 0-5 or 0-20 volts DC. Perfect for building thermostats, automatic battery disconnects, light level sensors, current-controlled switches, charge controllers, and humidistats. Backed by a full 1 year warranty.
- Ultra low battery drain
- Rugged reliable design
- Single channel model lacks the relay "strapping" feature offered with the dual channel model
- 10 amp latching relay outputs draws no power except when switching which drastically reduces power consumption
- Easy to program, simply press the Set Von and Set Voff buttons to memorize your desired turn on and turn off voltages
- 8-bit microcontroller / 10-bit ADC provides a resolution of 1024 increments for precise, repeatable control
- Non-volatile EEPROM memory stores your settings indefinitely, even without DC power applied
- Includes 1 thermistor which allows the unit to be used right out of the box as a thermostat
- Complete instructions offer example applications, operating instructions, trouble shooting tips, electrical/mechanical specifications and warranty info
