High-Power Modular Systems: The DHP Series
The DHP (Digital High Power) Series is engineered for high-capacity industrial testing requiring high power density in a modular 3U rackmount profile. This series covers power levels from 1980 W up to 6600 W. For lower-voltage, high-current applications, the orensen (Ametek) DHP 50-40 provides up to 50 V and 40 A, while the orensen (Ametek) DHP 30-66 delivers up to 30 V and 66 A. For mid-range and high-voltage needs, the series includes the orensen (Ametek) DHP 80-25 (80 V, 25 A), the orensen (Ametek) DHP 100-20 (100 V, 20 A), the orensen (Ametek) DHP 400-5 (400 V, 5 A), and the high-capacity orensen (Ametek) DHP 60-110 (60 V, 110 A).
These digital power supplies feature front-panel diagnostic displays showing output power, voltage, current, AC input voltage, and air inlet temperature. Safety and protection are central to the design, with overvoltage, overcurrent, and over-temperature protection. Additionally, features like power-off memory—standard on models such as the orensen (Ametek) DHP 40-75 and orensen (Ametek) DHP 600-11—restore previous settings upon startup, facilitating automated test sequencing.
High-Density ATE and OEM Integration: DCS and DLM Series
For applications where rack space is limited, Sorensen offers two highly compact switch-mode series:
- DCS Series: The Direct Current Source (DCS) series fits up to 1089 W into a slim 1U full-rack chassis. Featuring high-frequency switching technology, it delivers stable, continuously variable output. The orensen (Ametek) DCS20-50E provides 1000 W (20 V, 50 A) with under 1 ms transient recovery time, while the orensen (Ametek) DCS33-33E delivers 1089 W (33 V, 33 A) of power. For higher-voltage requirements, options include the orensen (Ametek) DCS40-25 (40 V, 25 A) and the orensen (Ametek) DCS600-1.7 (600 V, 1.7 A).
- DLM Series: For even tighter configurations, the DLM series packages up to 600 W of power into a 1U half-rack chassis. Utilizing Zero Voltage Switching (ZVS) technology to achieve low noise and high efficiency, units like the orensen (Ametek) DLM40-15 (40 V, 15 A, 600 W) and the orensen (Ametek) DLM 5-75 (5 V, 75 A, 375 W) are optimized for high-density system integration.
Rugged Industrial Reliability: The DCR Family
The DCR series consists of heavy-duty, phase-controlled Silicon Controlled Rectifier (SCR) power supplies built for maximum thermal and electrical resilience. Operating across wide temperature ranges (0 to +70 °C), these rugged units are ideal for burn-in and industrial processes. The family scales across multiple voltage classes:
- Low-voltage, high-current regulation is represented by the orensen (Ametek) DCR40, which offers up to 5000 W maximum output power on the highest-capacity model.
- Mid-range voltage regulation includes the orensen (Ametek) DCR60, orensen (Ametek) DCR80, and orensen (Ametek) DCR150 models.
- High-voltage industrial needs are covered by the orensen (Ametek) DCR300 and orensen (Ametek) DCR600 series, providing up to 300 V and 600 V respectively.
Standard configurations feature dual analog meters for straightforward monitoring, though digital LED meters are available as options.
Precision Benchtop and Lab Power: XT and XPH Series
For laboratory bench work where noise performance is critical, linear and hybrid regulation architectures are preferred:
- XT Series: The orensen (Ametek) XT Series - 60W provides highly regulated, low-noise linear power. It limits output voltage ripple and noise to just 1 mV RMS, with a rapid transient recovery time of under 50 µs, making it suitable for sensitive analog circuitry.
- XPH Series: The orensen (Ametek) XPH Series - 175 to 420W leverages a hybrid mixed-mode regulation system. By combining a switch-mode pre-regulation stage with a linear post-regulation stage, these supplies maintain high operational efficiency while preserving clean, low-noise output characteristics.

Frequently asked questions
- What are the primary differences between the DCS and DCR series?
- The DCS series (such as the orensen (Ametek) DCS60-18E and orensen (Ametek) DCS40-25) utilizes high-frequency switching technology in a compact 1U rackmount form factor, delivering high power density with dual digital displays. The DCR series (such as the orensen (Ametek) DCR60) uses phase-controlled SCR technology, resulting in a heavier, highly ruggedized chassis with analog metering, designed for maximum reliability in harsh environments and operating up to 70 °C.
- Which series is best suited for applications requiring low noise?
- The orensen (Ametek) XT Series - 60W linear power supply is designed specifically for low-noise applications, featuring a voltage ripple and noise specification of only 1 mV RMS.
- Can these power supplies be integrated into automated test systems?
- Yes. Most models offer standard analog remote control, and many support digital interfaces. For instance, the orensen (Ametek) DHP 300-6.6 comes standard with GPIB (IEEE-488.2), RS-232, and Isolated Analog interfaces, while models in the DLM series offer optional GPIB and RS-232 cards.
