Introduction
Thank you for selecting the Extech DCP36 laboratory grade 80W Switching DC Power Supply. The
DCP36 is auto-ranging and offers a 0.5~36V and 0~5A output capability. Its maximum current
output at 36V is 2.2A (80W/36V). The maximum voltage output at 5A is 16V (80W/5A).
The voltage/current spectrum is greater than three conventional power supplies of the same
power rating. Adjustable Upper Voltage/Current Limit features protect sensitive devices from
wide output variations. Three user presets allow for easy programming and recall of commonly
used output configurations. Master/Slave capability for up to 30 units in parallel connection. The
DCP36 is perfect for benchwork, field service, and hobbyists.
The DCP36 is shipped with the following accessories: AC power cord, RJ11 cable, alligator clip test
leads, and an RJ11 terminator plug.
This power supply is shipped fully tested and calibrated and, with proper use, will provide years of
reliable service. Please visit the Extech website for the latest user manual and for customer
support.

Display Descriptions
Constant Voltage mode (C.V. indicator)
The output voltage is kept constant at the set voltage. The
DCP36 remains in CV mode if the load current is lower than
the set current limit, otherwise it will switch to CC mode.
Constant Current mode (C.C. indicator)
When the load is higher than the set current limit of the set
voltage in CV mode, the Constant Current mode is active.
The output current is kept constant at the set current level
provided that the loading is sufficiently large to draw
current equal to or larger than the set current, otherwise it
will switch to the CV mode.
