Product Advantages:
(1)High efficiency
APM programmable 75VDC source has an operating efficiency
of up to 91%. 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
75VDC 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 75 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.
