Common Design and Protection Architectures
The Sorensen DHP Series is built on a modular design framework, with models featuring a standard 483 mm wide chassis. Most of these units share a compact 3U (133 mm) height. The series incorporates an expansive suite of protection features to safeguard connected loads, including Overvoltage Protection (OVP), Overcurrent Protection (OCP), and Overtemperature Protection (OTP), as well as Soft Start and Brown Out protection. Models like the DHP 30-66, DHP 60-110, DHP 80-25, and DHP 600-11 also feature Surge Limit protection to manage incoming power transients.
For automated setups where settings must remain tamper-proof, the DHP 30-66, DHP 100-20, and DHP 600-11 provide a Front Panel Lockout function. This feature disables manual front-panel inputs during remote execution. Furthermore, several models (including the DHP 30-66, DHP 40-75, DHP 80-25, and DHP 600-11) feature Power-Off Memory, restoring previous operational parameters via a dedicated LAST SET button once input power is enabled.
Voltage and Current Classifications
The family is divided into distinct voltage and power levels to suit specific application spaces:
- High-Current, Low-Voltage: For low-voltage high-current applications, the DHP 30-66 (30 V, 66 A, 1980 W), DHP 40-75 (40 V, 75 A, 3000 W), and DHP 50-40 (50 V, 40 A) are optimized for high-amperage testing. The high-capacity DHP 60-110 extends this range up to 60 V and 110 A, delivering 6600 W of power.
- Mid-Range Voltages: Mid-voltage applications are supported by the DHP 80-25 (80 V, 25 A, 2000 W) and the DHP 100-20 (100 V, 20 A, 2000 W).
- High-Voltage, Low-Current: For high-potential applications, the DHP 300-6.6 (300 V, 6.6 A, 1980 W), DHP 400-5 (400 V, 5 A, 2000 W), and DHP 600-11 (600 V, 11 A, 6600 W) offer stable voltage control up to 600 V.
Remote Control, Regulation, and Metering
Interface options differ by model to integrate cleanly into diverse automated test systems. The DHP 40-75 and DHP 300-6.6 come standard with GPIB (IEEE-488) and RS-232 connectivity, whereas the DHP 80-25 and DHP 100-20 provide RS-232 standard with optional GPIB upgrades. The DHP 60-110 offers standard Analog and RS-232 interfaces with optional GPIB, and the DHP 600-11 comes standard with analog programming.
Precise control is maintained through tight regulation specifications. The DHP 40-75 and DHP 300-6.6 exhibit voltage and current line/load regulation of 0.1% of maximum ratings. The DHP 300-6.6 is equipped with a highly visible Vacuum Fluorescent Display (VFD) and limits ripple and noise to 150 mV Vrms (20MHz).
Frequently asked questions
- Do these power supplies remember their settings after power loss?
- Yes. Models like the DHP 30-66, DHP 40-75, DHP 80-25, and DHP 600-11 include a Power-Off Memory function. Pressing the LAST SET button restores previous parameters as soon as input power is enabled.
- Are the front-panel controls disabled when operating under remote control?
- Yes, several models, including the DHP 30-66, DHP 100-20, and DHP 600-11, feature a Front Panel Lockout that disables front-panel controls during remote operation to prevent manual interference.
- Can the output of these units be shut down externally?
- Yes, models such as the DHP 50-40, DHP 30-66, DHP 40-75, DHP 300-6.6, DHP 80-25, and DHP 100-20 feature an external shutdown control input designed to remotely inhibit the power supply output.
