Sorensen DLM Series Programmable DC Power Supplies
2 models with full specifications from orensen (Ametek).
This page covers the Sorensen (Ametek) DLM 600W series of high-density programmable DC power supplies, specifically focusing on the DLM 5-75 and DLM40-15 models. Designed for demanding test and measurement applications where bench or rack space is limited, these supplies house high-density power performance in a compact 1U, half-rack chassis. Both units operate from a universal single-phase input of 90 to 264 VAC at 47 to 63 Hz, making them suitable for global utility environments. This guide assists engineering and procurement professionals in selecting the correct configuration based on output voltage, current capacity, and control interface requirements.

Common Platform Architecture
The DLM Series features a highly compact physical footprint, with the DLM40-15 measuring 216 mm wide, 44 mm high, and 330 mm deep, conforming to standard 1U half-rack dimensions and weighing 4.2 kg. This design allows for high-density integration in standard test racks or minimal footprint on a test bench. Both the DLM 5-75 and DLM40-15 support single-phase AC inputs from 90 to 264 VAC, enabling international operation without manual line voltage select switches. Standard configurations provide standard analog control interfaces, while multiple optional digital communication pathways are supported.
Output Capabilities and Model Differences
The individual models differ primarily in their output voltage and current ranges to accommodate various electrical loads. The DLM 5-75 provides a low-voltage, high-current output range from 0 to 5 VDC and 0 to 75 A, delivering a maximum output power of 375 W. This unit utilizes Zero Voltage Switching (ZVS) technology to achieve low noise and a typical full-load efficiency of 69% with a maximum input current of 6 A RMS at 90 VAC.
Conversely, the DLM40-15 supplies a continuously variable output from 0 to 40 VDC and 0 to 15 ADC, delivering a maximum power of 600 W. The DLM40-15 features active power factor correction, dual 3.5-digit LED displays for voltage and current, and a certified operating temperature range of 0 to 50 °C.
Control and Integration Interfaces
Integration into automated test environments is facilitated by multiple interface options. For the DLM 5-75, options include the M9G GPIB interface, the M9C RS-232 interface, and the M51A isolated analog interface, which allows selectable 0-5V, 0-10V, or 4-20mA control. The DLM40-15 comes standard with an analog interface, but can also be configured with optional GPIB and RS-232 interfaces via the M9G interface option.
