Product Description
Product
Introduction:
High precision variable dc power supply 120V has a Foldback protection function, which is used to turn off the output when the power CV/CC is switched to protect certain DUTs that are sensitive to voltage overshoot and current overshoot. The user can specify the working mode and set the protection delay time. If the current working mode is switched, the protection will be triggered when the delay time is exhausted, and the output will be turned off.
Except the 120v Dc Power Supply,it could be also have higher voltage opition for 150v Dc Power Supply,200v Dc Power Supply,kindly check more with the regional sales.

Product Advantages:
(1)High efficiency
APM programmable 120VDC 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 120VDC 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 120
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.
