Ordering Guide

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
