| Regulation |
Line: For input voltage variation over the AC input voltage range, with constant rated load.
Load: For 0-100% load variation, with constant nominal line voltage.
Voltage: 0.05% of maximum rated output +2mV
Current: 0.1% of maximum rated output |
| Transient Response |
Typically recovers in 1.5 ms to within 1% of steady-state output voltage (greater than 50% of Vmax) for 70-100% or 100-70% load change. |
| Stability |
±0.05% of maximum voltage or current over 8 hours after 15 minute warm-up time at fixed line, load and temperature. Current accuracy for 5V, 8V, and 16V models is 1% typical. |
| Efficiency |
5-8V Models: 82% typical
16-80V Models: 87% typical
150-600V Models: 85% typical (at maximum output power) |
| Temperature Coefficient |
0.02%/°C of rated output voltage; 0.03%/°C of rated output current.
Change in output per °C change in ambient temperature, with constant line and load. | |

| Remote Sense |
The maximum total allowed sense line drop is 2V for 5V, 8V and 16V models and 5V for all other models. Line drop subtracts from the maximum available output voltage at full rated power. |
| Remote Sense Protection |
Unit will not be damaged due to misconnection of the remote sense leads. |
| Remote Programming |
Voltage, current (0-100%) and OVP (5-110%) of full scale can be programmed by selectable 0-5 VDC, 0-10 VDC, or 0-5 kÙ. |
| Remote Monitoring |
Voltage or current can be monitored with user-selectable ranges, 0-5 VDC or 0-10 VDC |
| Operational Features |
Master/slave parallel* operation, up to 2 units can be connected in parallel with active current sharing control to within 10% of each supply. Series operation, up to 3 units of the same model type can be connected in series (consult manual). Negative terminal rated at 150 Vmax above ground |

The DLM 3 kW and 4 kW Series programmable DC power supplies are designed to provide highly stable, continuously variable output voltage and current for a broad range of applications in a compact 2U ( 3½” high) chassis.
The 4 kW power rating is new to the Sorensen Family of power supplies. Both the 3 kW and
4 kW models have output voltages from 0-5 VDC to 0-600 VDC and a current range from 0-5A to 0-450A. The output RMS noise is as low as 10 mV. The output will recover to 1% of its steady-state voltage within 1 ms for a step load change of 100% to 70% or 70% to 100%. The front panel layout makes the series extremely easy to use. Control switches include: power on, enable/ standby and local/remote.
Displays and indicators show programmed set points and operational control status. The programmed voltage, current and overvoltage set points are displayed with two large 3½ digit LED displays. Operational Status LEDs indicate power on, shutdown, overtemperature, overvoltage, constant current and voltage mode status. Control Status LEDs indicate front panel lockout, remote control and standby status. IEEE-488.2 control LEDs indicate error, service request and remote address status.
The 3 kW Models will accept 200*/230 VAC single phase and 200*/208 VAC three phase input power.
The 4 kW Models will accept 200*/208 VAC, three phase or optional 400 or
480 VAC three phase input power.
*Operating temperature below 40°C
