Newmar’s Model EP-12-70 power system enclosure was developed for 12- and 24-volt radios and batteries installed in outdoor enclosures that are rated by the National Electrical Manufacturers Association, or NEMA. It features a low-voltage battery disconnect, alarms and a circuit that adjusts the charge controller activation points based on battery temperature. The company’s CPS-20 computer power sentry monitors vehicle voltage. It also sends alerts to mobile computer operators when system shutdown is imminent and automatically saves data. If the vehicle is unattended, shutdown sequence is automatically initiated, according to the company. The TMR-30 power timer prevents power drain from vehicle batteries due to radios and other equipment being left on.
