1. Introduction and Features
Thank you for selecting the Extech DCP42 Switching Mode Power Supply. This newly re-designed
laboratory grade power supply differs from a conventional power supply in that it can calculate
and change the voltage and current limit points according to the available maximum power.
Therefore the maximum limits of the voltage and current are changeable according to the rated
power. A conventional power supply has only a set maximum voltage and current such that all of
the operating V & A must fall within these limits. The DCP42 offers cost saving and space saving
advantages as one constant-power power supply can do the work of several conventional power
suppliers.
The DCP42 is highly efficient, incorporates upgraded SMPS circuitry with small form factor, benefits
from an automatic cross-over for CC and CV, has three (3) Voltage/Current presets, and can be
remote controlled. The DCP42 is perfect for solving a variety of loading conditions and applications.
Features include the following:
Dual action (Course/Fine) tuning provides smooth, accurate, and quick setting of
Voltage/Current
Setting, changing, and verifying the current limit level is convenient and can be
performed without output pole spiking
The Remote Control feature permits output ON/OFF and Voltage/Current adjustments
without the need to touch the front panel of the power supply
The USB port offers PC connectivity for programming and running ramp/soak cycles with
20 programmable sets of Voltage/Current and varying test durations (up to 999 cycles)
The DC ramp and waveform generator can either be panel set or set by the supplied
software which previews the final waveform.
Applications and industries where the DCP42 can be employed include laboratory,
telecommunications, production testing, field testing, DC network powering, and more
Three (3) user programmable Voltage/Current settings offer quick recall of frequently
used test settings
The DCP42 is suitable for a wide range of applications such as laboratory, production
testing, field test of remote critical voltage loads, powering of dc networks, and more.
This device is shipped fully tested and calibrated and, with proper use, will provide years of
reliable service. Please visit our website to check for the latest version of this User Guide, Product
