3. Introduction
This series of Programmable Switching Mode Power Supplies are designed for full remote
programming with data logging functionality. Up to 31 power supplies can be connected via RS- 485. It
is ideal for applications which require various groups of output settings and running periods for
repetitive tests especially with multiple power supplies.
The front panel allows users to all programming and output settings as a stand alone laboratory power
supply.
Full command sets are given in this manual to facilitate the integration of your own control software.
This series of power supplies have obtained the safety approval EN-61010 and EN-55011 EMC
approval for scientific , industrial equipment of the CE directives.
Please keep this manual in a safe place and contact your vendor for any special requirement in
optional accessories for RS-485.
NOTE:
Laboratory Power Supplies are not designed for charging batteries. Any use of this type can cause
serious damage to the device, which are exempt from any legal claims whatever.
