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

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.
Generator Starter
Advanced generator control based on battery voltage.

The Model GS-2 Universal Generator Starter is used to automatically start and stop your generator at user settablebattery 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.
The Model GS-1 is the same as the GS-2 but without an enclosure (PC board only).
12 Volt DC Isolater

908-009 200 mA, 10.5 to 14.5 VDC $39
This DC isolater is primarily used to isolate a DC phone answering machine. The phone lines are positively grounded, while your electrical system is negatively grounded. This causes the answering machine to disconnect upon activation if not isolated from the positive ground.
12V or 24V Single Event Timer

909-008 6 Amp
12V or 24V Timer $39
Programmable 12V Timer
909-007 Series 884 Timer $69
With this timer you can control up to 16 amps (45° C) at up to 250 volts AC or 36 volts DC. It is a 7 day 8 event timer. Once the timer is connected to 12 volts and reset, its internal battery will maintain its quartz clock and programming for up to 5 years. However, it must be connected to a 12 volt source for it switching functions to work. It only functions as a switch with no normally closed contacts. Dimensions: 2 3/4" x 2 3/4" x 2 1/2" deep.
