Sorensen DCS Series Programmable DC Power Supplies

5 models with full specifications from orensen (Ametek).

The Sorensen DCS (Direct Current Source) Series by AMETEK is a family of 1 kW-class programmable switch-mode DC power supplies. Engineered for ATE system integration, laboratory research, and OEM testing applications, these devices combine high power density with a slim form factor. This guide outlines the key performance metrics and structural options of the series, comparing five models: the orensen (Ametek) DCS20-50E, orensen (Ametek) DCS33-33E, orensen (Ametek) DCS40-25, orensen (Ametek) DCS60-18E, and orensen (Ametek) DCS600-1.7.

While sharing a common mechanical footprint and weighing exactly 8.6 kg, these models feature varying internal configurations, output capacities, and control interfaces designed to meet distinct voltage and current testing requirements.

Output Profiles and Load Capabilities

The DCS series spans a broad spectrum of voltage and current ranges, enabling precise selection based on application requirements:

  • High-Current Models: The orensen (Ametek) DCS20-50E provides a 0 to 20 VDC output at up to 50 A (1000 W max), making it suitable for low-voltage, high-current subassembly testing.
  • Mid-Range Models: The orensen (Ametek) DCS33-33E delivers 0 to 33 VDC at up to 33 ADC (1089 W max), while the orensen (Ametek) DCS40-25 outputs 0 to 40 V at up to 25 A (1000 W max). The orensen (Ametek) DCS60-18E increases output voltage further to 0 to 60 VDC at up to 18 ADC (1080 W max).
  • High-Voltage Model: For high-voltage applications, the orensen (Ametek) DCS600-1.7 offers 0 to 600 Vdc with a current output limit of 1.7 Adc (1020 W max).

Models such as the orensen (Ametek) DCS40-25 and orensen (Ametek) DCS600-1.7 feature automatic crossover between Constant Voltage (CV) and Constant Current (CC) modes, and remote sense compensation of up to 1 V per lead.

Power Input and Environmental Specifications

The input power requirements vary significantly depending on the model chosen:

  • The orensen (Ametek) DCS20-50E and orensen (Ametek) DCS33-33E feature universal active power factor correction (PFC) inputs that operate from 85 to 264 VAC (single-phase, 47 to 63 Hz).
  • The orensen (Ametek) DCS40-25 and orensen (Ametek) DCS600-1.7 feature user-selectable 115/230 Vac single-phase inputs.
  • The orensen (Ametek) DCS60-18E requires a single-phase high-line input of 190 to 250 VAC.

All five models operate reliably within a temperature range of 0 to 50 °C. For the orensen (Ametek) DCS33-33E, output power derates linearly to 50% capacity when operating between 50 °C and 70 °C.

Control Interfaces and Display Options

All units feature front-panel digital displays. The orensen (Ametek) DCS20-50E, orensen (Ametek) DCS33-33E, orensen (Ametek) DCS60-18E, and orensen (Ametek) DCS600-1.7 use dual 3.5-digit LED digital displays to simultaneously report voltage and current. The orensen (Ametek) DCS40-25 similarly provides simultaneous digital readings.

Analog control is the standard interface option for most models. For digital system integration, optional interfaces are available:

  • GPIB/IEEE-488: Optional across all models, including the orensen (Ametek) DCS40-25 and orensen (Ametek) DCS600-1.7.
  • RS-232: Optional on the orensen (Ametek) DCS20-50E and orensen (Ametek) DCS60-18E.
  • Ethernet/LXI: Optionally supported on the orensen (Ametek) DCS20-50E.
  • Multi-Channel Control: Available as an option specifically for the orensen (Ametek) DCS60-18E.
