West Mountain Radio PWRguard Plus DC Protectors
West Mountain Radio PWRguard Plus DC Protectors are solid-state series switches that automatically detect and disconnect when a DC power system fault occurs, including over-voltage, under-voltage and short circuit conditions. Designed specifically to protect your radio, power supply and battery backup from damage, PWRguard Plus instantly turns off if the DC line exceeds 15 volts or drops below 11 volts for more than 3 seconds, and automatically or manually reset when the line returns to 13 volts or above. Momentary voltage dips below 11 volts are ignored to prevent false tripping while transmitting. PWRguard Plus DC Protectors have Powerpole connectors for input and output and handle 30 amperes continuous duty and 40 amp peaks and feature a soft turn-on solid-state circuit with no relay contact bounce, to protect equipment from in-rush current and spikes. LEDs indicate system conditions and a mutable piezo buzzer sounds every minute when PWRguard Plus turns the DC power off due to a system problem. In addition to protecting your equipment, battery and power supply from self-inflicted trouble, PWRguard Plus DC Protectors also have a sense input connection inside that can be wired to a switch, contact closure or can be triggered by a 3 to 5 volt DC. This means, PWRguard Plus can also be controlled with a Key Locking Switch to prevent radio operation during down time, system or antenna repairs, cut power based on input from a water or a heat sensor, or turn power on or off with a photo-electric circuit or other low current sensor switch; only your imagination can limit the useful applications for the PWRguard Plus!

Ideal for radio communications systems that rely on DC power, West Mountain Radio PWRguard Plus DC Protectors are a very useful addition to almost any 12 Volt DC powered system.

West Mountain Radio ISOpwr+ Auxiliary Battery Isolators
West Mountain Radio ISOpwr+ Auxiliary Battery Isolators protect the primary battery while supplying power to the "spare" battery and equipment. With an ISOpwr+ isolator, the vehicle battery will never be drained by leaving the equipment turned on, so the vehicle will always start! ISOpwr+ Isolators are automatic solid-state ON-OFF switches, without relays, that charge an auxiliary battery and run mobile radio equipment, powered by the vehicle alternator when the car is running. The ISOpwr+ turns ON when the car is running and the line is over 13.3 volts. The ISOpwr+ turns OFF when the alternator is not running and the vehicle battery has fallen below 12.6 volts, but equipment will continue to run from the auxiliary battery. ISOpwr+ Auxiliary Battery Isolators work safely with all types of batteries including 12-volt standard Lead-Acid, Flooded Lead Acid, Gelled and AGM. They are ideal for use in all vehicles utilizing an auxiliary battery, for many diverse purposes: Radio Command mobile set ups for ARES, RACES, FEMA; contest VHF/UHF rovers; medium powered Amateur Radio equipment; re-charging stations for electric model airplanes, boats and cars; DC powered TVs or stereos in RVs and campers, and so much more! ISOpwr+ isolators may be used without an auxiliary battery, as a power interrupt, to automatically turn on a transceiver or other device only when the car is running. In this battery saving application, the radio will turn off automatically after a short delay when the vehicle ignition is turned off, so you won't have to remember to turn off the transceiver. ISOpwr+ features a USB port for setting operating thresholds and for monitoring and has a smaller and lighter weight enclosure. West Mountain Radio ISOpwr+ Auxiliary Battery Isolator Specifications: Operating Voltage: 20 V maximum Quiescent Current: Less than 5 mA Maximum Current: 40 A Voltage Drop: 0.25 V at 1A, diode drop Series Resistance: 0.01 ohms maximum Switch Time-Constant: 5 seconds Turn ON Threshold: 13.3 Vdc (+/- 0.1 V) Turn OFF Threshold: 12.6 Vdc (+/- 0.1 V) Green LED: Indicates the ISOpwr+ output is ON Size: 4.50 x 3.40 x 1.40 in, 11.4 x 8.6 x 3.5 cm Weight: 0.9 lbs., 0.4 kg Connectors: Powerpoles Enclosure: Heatsink, black anodized aluminum, painted aluminum cover Note: For additional product information, please look at the files under the "Documentation" tab.
