Remote Start/Stop and Interlock |
TTL compatible input or 12-250 VAC (12-130 VDC) or a contact closure |
Cooling |
Internal fan, over temperature shutdown if internal heat sink exceeds set temperature |
Remote Sense |
The maximum allowed sense line drop is 4V per line (2V on the DCS 8/10V 1 kW/1.2 kW models and 1V/line for all 3 kW models). Line drop subtracts from the maximum available output voltage at full rated power. |
Remote Programming |
Enabled via external jumper on rear panel connector J3 |
Overvoltage Protection |
Crowbar type adjustable from 5-110% of rated output using front panel control (local or remote program selectable via J3 jumper) |

Transient Response |
Typically recovers in 500 μs (1 & 1.2 kW) or 1ms (3k W) to 1% of steady-state output voltage (within 1% of Vmax) for 70-100% or 100-70% load change. |
Stability |
±0.05% of maximum voltage or current over 8 hours after 30 minute warm-up time at fixed line, load and temperature |
Efficiency |
See table below Temperature Coefficient: 0.02%/°C of maximum output voltage; 0.03%/°C of maximum output current. Change in output per °C change in ambient temperature, with constant line and load |
