DC Automatic Switching and Conversion

Voltage Controlled Switches

An adjustable voltage relay switch, available Active High, or Active Low.

792-010 Open Frame-Activate High $89

10-60V 30A VCS-1AH

792-011 Enclosed-Activate High $139

10-60V 30A VCS-2AH

792-010 Open Frame-Activate Low $89

10-60V 30A VCS-1AL

792-013 Enclosed-Activate Low $139

10-60V 30A VCS-2AL

These voltage controlled switches are activated when the battery bank voltage reaches a user adjusted set point. The "Activate High" model is commonly used to turn on a battery vent fan. The "Activate Low" model can be used as a load controller. Both versions work at 12, 18, 24, 36 and 48 volts VCS-1AH

DC. They can switch up to 30 amps. A thorough instruction manual complete with various hook-up diagrams is included.

Dimensions:

Open Frame: 5.2 L x 2.9" W x 1.8" H

Enclosed Unit: Approx. 10"L x 6"W x 2.5" H

Generator Starter

Advanced generator control based on battery voltage.

792-001 Enclosed 12-48 VDC $399

The Model GS-2 Universal Generator Starter is used to automatically start and stop your generator at user settable GS-2 (Dscn0007)

battery bank voltage levels. This unit supports 2, 3 and 4 wire systems as well as incorporating advanced control systems for glowplug activation or load control. Relay activation is indicated by LED's for precrank, crank, load, run, stop and fault. The unit is mounted in a NEMA 3R box: 10" x 8" x 4" deep.

24/48 VDC 10A EQ-24/48-10

These devices are used to convert DC voltages from one voltage to another. They are unique as they can be used in either direction. They can also be used as a battery equalizer; for example taking a 12 volt tap from a 24 volt battery bank.

The models we stock deliver a fixed, user settable output for a range of input voltages. For example, 13.8 volts output from a nominal 24 volt battery bank which really operates between 24 and 29 volts. Other voltages and current levels are available including versions whose output voltage is proportional to its input voltage. All versions operate at greater than 95% efficiency.

The devices are mounted in a weathertight NEMA 4 enclosure which measures 4.5"L x 2.9"W x 2.6" H.

The devices listed on this page are designed and manufactured by Solar Converters Inc. in Canada. They offer a number of other devices for DC control including power tracker charge controllers, cathodic protection devices, linear current boosters and pump controllers. All their products seem very well designed and come with a one year warranty. Please call if you have an interest in one of these other devices.
