|
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
