Water Tight Cathodic Protection Rectifier, Model ES-WT

All completed units are pressurize-tested under water for leaks.
  •    
    Farwest's Model ES-WT is a watertight rectifier for use in underground utility vaults that are subject to flooding. With a maximum output of 200 watts, Model ES-WT can be used where conventional rectifiers would fail in flooding conditions.     All completed units are pressurize-tested under water for leaks.

  • ES Utility Line Rectifier Ordering Guide

    Configure an 8-position model number like ES-I-V 20-5
    Positions from left to right are as follows:

    Position #1: Model

    ES-I = ES Utility Rectifier

    ES-II =ES Utility Rectifier

    Position #2: Output Control Type

    S = Standard Rectifier (Manual taps)
    V = Variac Control
    E = Constant Voltage Control (ES-II only)

    D = Constant Current Control (ES-II only)
    P = Constant Potential Control (ES-II only)
    M = Multiple Modes (ES-II only)

    Position #3: DC Output Voltage*

    List DC Voltage Desired (6V, 12V, 20V, 30V or 40V)

    Position #4: DC Current Output*

    List DC Current Desired (5A or 10A))

    Position #5: Special or Optional Features

    H = Hour Meter (ES-II only)

    K = Red or Green Status Lights ((ES-II only)
     
    * Combinations are 6V-5A, 6V-10A, 12V-5A, 12V-10A, 20V-5A, 20V-10A, 30V-5A,  40V-5A
