OVERVIEW

The DCS Series of precision DC power Supplies uses state of the art field programmable logic array (FPGA) technology to implement a digital power conversion topology that combines high efficiency with a rich feature set and excellent specifications. This results in 16-bit resolution precision for both set points and measurements throughout.
Packaged in a compact, standard 19” rack mount chassis, these powerful functions are easily accessible through an easy to use, large color touch screen based user interface from the front panel or by sending commands over one of several available digital control interfaces.

All DCS models are equipped with a flexible auto-ranging output stage which provides higher output voltage at lower output current, or higher output current at lower output voltage, always controlled by the adjustable power set value . Therefore, a wide range of applications can be covered by the use of just one DCS model. This also greatly reduces the need for 20 different voltage/current combination models as is typical for conventional DC power supplies.

The DCS Series power sources are reliable and cost effective solutions for all of your DC power design and test needs!

APPLICATIONS

DC Test Power

The DCS Series programmable Power Sources use state-of-the-art DSP technology to provide stable and accurate output, regardless of AC input line conditions. careful filtering and digital power controls ensure class leasing output noise levels at these power levels.  The large TFT touch screen supports all user interactions with the help of just two rotary knobs. A decimal keypad pop-up allows direct entry of parameters as well.  Both output setting and measurements can be displayed on the display in large fonts, visible from a distance if needed.

Telecom Power Converter Test and Burn-in

The wide operating range of the DCS power supplies, make possible by their auto-ranging output is ideal for testing modern DC/DC converters that can accept a wide range of DC input voltages.  Since the same DCS model can support low voltage at high current as well as high voltage at low current, there is longer any  need to oversize the DC supply used. This results in significant cost savings.

Battery Forming

With its high power density and programming battery charging profiles, the DCS series can be used for forming large batteries up to 1500Vdc. When combined with APS’s 6RL series of regenerative DC loads, a cost effective complete battery test system can be configured using the Master/Slave mode of both units.

Product Development and Test

With the ability to provide programmable over-voltage, over-current and over-power, the DCS power supply can safely be used to power up early prototypes without feat of  losing time or money due to scarce prototype failure.

PV Inverter Testing

With models available to 1500Vdc output, a wide assortment of photo-voltaic inverters can be tested by replacing actual PV panels and light sources with a programmable DC power supply. The built-in function generator of the DCS can be used to simulate a wide range of PV characteristics including ISC, UOC, UMPP, IMPP and Irradiance.

Avionics Power

Capable of supporting 28Vdc and ±270Vdc (using 2 units in master/slave series), the DCS Series is a good choice for testing DC power avionics products as well.
