Thank you for buying the
PS23003A
! The
PS23003A
is a DC-regulated power supply with two independent outputs
and manual voltage selection. There are two voltage ranges, viz. 0-15V and 15-30V. The output current is adjustable
between 0-3A in the constant current mode or C.C. mode.
The
PS23003A
is a compact, stable and reliable device. It is ideally suited for educational and industrial
environments and for use in laboratories.
