Imark Communications SR solar regulators

The SR solar regulators, for use with remote-area power systems, are designed to operate with popular RAPS inverters and are suitable in harsh remote locations.

The regulators are pulse-width modulation shunt regulators, for efficiency, and use heavy-duty low-loss diodes and MOSFET power components.

There are three models available for 48, 120, and 240 V DC (nominal) systems with nominal power capabilities of 5, 12 and 16 kW.

The regulators have LEDs to show system operational status and illuminated panel meters show battery voltage, charge current and battery temperature. The battery-over-voltage protection circuit and the heatsink overtemperature protection will both trip the heavy-duty PV input circuit breaker if the settings are exceeded.

Substantial surge protection is included on the PV inputs with status indication on the front panel. Heavy-duty binding posts on the rear panel allow PV, battery and earth connections. A 12-way interface connector is also provided for connection of the battery temperature sensor or external interfacing with other equipment.

The regulators are housed in a 19″ 4RU cabinet, which can be either wall or rack mounted. The cabinet includes a fan-forced cooling chamber.
