Load Bank Systems : Solar-5

  Solar-5 Overview

Simplex Load Bank System - Solar-5

The Simplex Solar-5 is a very large capacity, resistive/inductive portable load bank capable of 0.8 power factor loads to 5.0MVA (4.0MW, 3.0MVAR). The Solar-5 is designed for low voltage application to 690vAC. PLC based digital load control with touchscreen operator interface is standard. The unit is network capable with other Solar Load Banks as well as most standard Simplex Load Banks in order to form large, ultra high capacity systems which can be controlled from a single operator interface with totalized data acquisition.

  Solar-5 Features

The Load Bank is a completely self-contained, freestanding unit which includes all load elements, load control devices, load element branch circuit fuse protection, main load bus and terminals, cooling system, control power supply, digital controller with data acquisition and malfunction detection system and weatherproof enclosure.
Resistive Load Elements
Simplex Powr Web: Open wire, helically wound, chromium alloy, load element thermally derated to 60%. 5% tolerance, 2% balance. .995 p.f. Element wire mechanically supported over entire length such that if a wire should break, the broken wire segments will not short to adjacent conductors or to ground. UL Recognized
Inductive Load Elements
Iron-core, non-saturable air-gap type, with aluminum windings, varnish/epoxy coated. 150°C rise. 220°C insulation
