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
