1.1 Description
The DLM–E Series 3000 and 4000 watt power supplies are designed to provide highly stable,
continuously variable output voltage and current for a broad range of development, system and
burn–in applications. Model numbers for this series are designated by the DLM prefix, followed
by the output voltage and current ratings. For example, the model number DLM40–100E
indicates that the unit is rated at 0–40 VDC and 0–100 amps while a model DLM8–350E is rated
at 0–8 VDC and 0–350 amps. The DLM–E Series employs high frequency switching regulator
technology to achieve high power density and small package size.
1.2 Operating Modes
The DLM–E Series supply has two basic operating modes: Constant Voltage and Constant
Current. In constant voltage mode, the output voltage is regulated at the selected value while
the output current varies with the load requirements. In constant current mode, the output
current is regulated at the selected value while output the voltage varies with the load
requirements.
An automatic crossover system enables the unit to switch operating modes in response to
varying load requirements. If, for example, the unit is operating in voltage mode and the load
current attempts to increase above the setting of the current control, the unit will switch
automatically from voltage mode to current mode. If the load current is subsequently reduced
below the setting of the current control the unit will return to voltage mode automatically.
1.3 Power Supply Features
•
3 kW and 4 kW models with voltage ranges from 0–5 VDC to 0–600 VDC and
current ranges from 0–5A to 0–450A.
•
3 kW models operate with either single or three–phase AC input power without
jumpers.
•
High input AC power factor, 0.95 typical, with three–phase 208, 400, or 480 VAC
inputs.
