orensen (Ametek)

The DHP series consists of high-power, modular programmable switching DC power supplies engineered for demanding test profiles. Models in this series include the orensen (Ametek) DHP 50-40, orensen (Ametek) DHP 400-5, orensen (Ametek) DHP 30-66, orensen (Ametek) DHP 60-110, orensen (Ametek) DHP 40-75, and orensen (Ametek) DHP 300-6.6.

These supplies utilize advanced digital monitoring and diagnostics, with vacuum fluorescent or digital displays showing voltage, current, output power, and inlet temperatures. The orensen (Ametek) DHP 60-110 delivers up to 6.6 kW (60 VDC at 110 A) in a 3U chassis using a 3-phase AC input, while the orensen (Ametek) DHP 40-75 offers 3 kW of output power. To support automated system setups, several models feature dedicated power-off memory (such as the orensen (Ametek) DHP 30-66 and DHP 40-75) to restore the last active settings upon power initialization, as well as an external shutdown capability to inhibit output remotely.

For applications requiring high power density in space-constrained layouts, the DCS and DLM series provide compact rackmount footprints.

• orensen (Ametek) DCS60-18E: A 1U rackmount model delivering 0 to 60 VDC at up to 18 ADC (1080 W) with standard analog interfaces and optional RS-232 or GPIB control.
• orensen (Ametek) DCS33-33E: This 1089 W unit operates from an active PFC universal input (85-264 VAC), outputting 0 to 33 VDC at up to 33 ADC with a low-profile 1U design.
• orensen (Ametek) DLM 5-75: Operating on a single-phase input from 90 to 264 VAC, this 375 W model uses Zero Voltage Switching (ZVS) technology to achieve low noise and high efficiency in a compact 1U half-rack chassis.

For high-power, industrial-grade reliability, the phase-controlled SCR-based DCR families deliver highly regulated DC power. These models are suitable for heavy-duty bench or rack applications:

• orensen (Ametek) DCR40: Offers adjustable output up to 40 VDC. Configurations like the DCR 40-125B provide up to 5000 W of output power. Typical transient recovery time is 50 ms to return within 150 mV of steady-state voltage for a 50% load step.
• orensen (Ametek) DCR80: Delivers stable DC power up to 80 VDC. Current ratings range from 4.5 A to 18 A, supplying up to 1440 W of power.
• orensen (Ametek) DCR300: Provides regulated output voltage up to 300 VDC. The DCR 300-9B model supports output current up to 9.0 Adc and a maximum output power of 2700 W.
• orensen (Ametek) DCR600: Reaches up to 600 VDC with model variations supporting up to 4.5 ADC (2700 W). Line and load regulation in voltage mode is rated at 0.05% of the maximum output voltage.

The orensen (Ametek) XPH Series - 175 to 420W consists of compact benchtop power supplies. These units use a hybrid mixed-mode regulation system that combines switch-mode pre-regulation with linear post-regulation. Available in single, dual, and triple output configurations, they include 4 mm safety binding posts for output connections. The series includes the XPH 35-5 (0 to 35 V, 0 to 5 A) and the XPH 35-4T, which features an auxiliary output switchable between 3.3 V and 5.0 V.
