Product Advantages:
(1)High efficiency
APM
programmable 20VDC source has an operating efficiency of up to 85%. In the
circuit design, switch tube is using zero (0) voltage conductor and when the
circuit is running, the damage inflicted on the device itself is reduced, and
subsequently increase the overall efficiency while lowering the rate of
temperature rise of the DC source. Compare with other similar types of product
in markets, APM Technologies' programmable DC source has an obvious
advantage.
(2)Ultrafast Respond
Time
The unique fast drop function makes the response of APM programmable DC
source much better than that of any other similar products available on the
market.

(3)DVM
measurement function
APM programmable DC source's built-in DVM independent
measurement function can measure the value of output voltage at the output
terminal, and display the value at VFD screen by switchover the front-panel
buttons. The DC source can also be used as external equipment in laboratory
testing to measure the voltage values.
(4)Master/Slave Control
In the
master-slave control mode, up to 10 units of APM programmable DC source can be
used in a series or parallel mode.
Master-slave control mode can realize the
effect as "a hundred responses to a (single) call". Once the master-slave mode
is settled, "SLAVE" will be locked in the main interface and exclusively
controlled by "MASTER". When there is a "SLAVE" signaling of protection mode,
all the DC sources will turn off and exit master-slave mode.
(5)Series Mode Functions
APM
programmable 20 VDC source via its RS485 interface can be operated by using up to 31 units of the device ,thus makes it possible to
simultaneously control all the DC sources connected on RS485 from PC.
