  Saturn-HV Medium Voltage Load Bank Overview

Simplex Load Banks - Saturn-HV Stationary Load Bank

The Saturn-HV is a self-contained Load Bank to 15KV utilizing the Simplex Saturn Load Module with on-board dry-type power transformer. It is a freestanding, skidded unit consisting of three principle sections:

1. High voltage section consisting of main input power terminals, high voltage: 480V 3-phase power transformer, low voltage output terminals, and outputs to load cell.
2. 480V, low voltage resistive load section consisting of one 1500KW-3000KW forced air-cooled load cell.
3. Control Section.

  Saturn-HV Medium Voltage Load Bank Features

Simplex Saturn-HV load banks can be used to satisfy the requirements of the National Fire Protection Association (NFPA) for emergency stand-by power systems.
Load Elements
Simplex Powr-Web chromium alloy, open wire, continuously supported, power resistor.
Elements mounted in slide-out trays.
UL Recognized
System Controls
Standard: Simplex D-Series Digital Controller with local or remote touchscreen.
Integral forced air cooling system.
Ultra-high volume forced air cooling system.
Air temperature rise limited to 150-200°F range.
Vertical airflow -- cold air intake at bottom, hot air exhaust at top.
