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.
