| Efficiency |
87% typical at full load, nominal line |
| Remote Control/Monitor |
On/Off control via contact closure, 6-120 VDC or 12-240VAC, and TTL or CMOS switch, current monitor, OCP limit set, summary fault status |
| Overvoltage Protection |
Fixed at approximately 110% of the rating compliance voltage. Reset requires cycling the front panel standby power switch off/on
Isolated Analog Control (option)
Input to Output Isolation: 500 V
Compliant with maximum terminal float voltage.
