The PSU505 is a DC power supply
with 3 programmable outputs and
12-bit resolution. The total output
power is 210 W: channels 1 and
2, 30V/3 A, provide 90 W each;
channel 3, 10V/ 5 A, puts out
30 W at a constant rate. Channel
1 provides outputs in serial and
parallel modes; channel 2, in serial
mode only. On channel 3, the

an alphanumeric keypad. With the
timer function, the user can control

user can perform auto-ranging,
a feature not found on traditional
power supplies.

The user can monitor OVP
(overvoltage protection) and OCP
(overcurrent protection) on the
front-panel LCD. Because of its

0.01% load-and-line regulation
and 50 ms max response time,
the PSU505 remains stable even
when the voltage source and loads
change. The PSU505 is also
highly efficient, with an average
measurement time of 50 ms.

The PSU505 is easy to use,
featuring an adjustable tracking
function, a rotary selection dial, and

when each output is switched off
(1 second to 100 hours); this feature
is particularly useful in burn-in-room
and electroplating applications.
Up to 100 configurations can be
stored in memory. A key-lock
function prevents users from
changing the original settings.
