DC power supply equipment for test 75V 1U

Basic Info

Model No.: 75VDC series(1U Type)

Product Description

Product Introduction:


APM offers cost effective Dc Power Supply unit. Wide range output Power Supply provides wider voltage and current range.One unit can replace several traditional rectangular power units ,then save cost and space. Users can realize diversified operation through front panel, free monitoring software or external control to meet different application requirements.


Areas of Application:

● LED Sector: Used for LED driver and LED product testing and burn-in test.

● Automobile Sector: Used for automobile electronics product testing,and simulation of the voltage waveform of automobile under different conditions.

● Medical Field:Used for medical device testing or it being integrated in medical equipment.

● Automatic Testing Sector: Can be integrated in automatic testing system to test electricity parameters, and to supply power to the products under testing.

● Communication Sector: Used for the tests of communication power supply and electronic devices.

● Aerospace Sector: Used for aviation electronic products testing and power supply.

● Household Field:Used for household products test.

● Scientific Research Sector:Used in scientific research units, colleges & universities,and certification institutions for laboratory testing and power supply.


Product Features:

● DVM independent measurement functions.

● Coded knobs, multifunctional keyboard.

● Standrad RS232/LAN/RS485/USB interface.

● Function of editing List waveform.

● Use SCPI commands.

● CE/UL/CSA/FCC certified.

● With accurate voltage and current measurement capability.

● Remote sensing to compensate for voltage drop in load leads.


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.
