Product details

Product Introduction:

APM 20VDC series is 0-1200W programmable dc power supply. OVP, OCP, OTP, and OPP protect the power supply and its loads from unexpected conditions. Has large LCD panel display output and parameter simultaneously and a key lock feature to prevent changing the settings. It is single output 15 volt power DC supply features wide-adjust output voltages from 0V-20V and offers output power range from 0-600W to 0-1200W.

Except the 20v Dc Power Supply,it could be also have higher voltage opition for 32v Dc Power Supply,40v Dc Power Supply,kindly check more with the regional sales.

Areas of Application:

● Automobile Sector: Used for automobile electronics product testing,and simulation of the voltage waveform of automobile under different conditions.
● LED Sector: Used for LED driver and LED product testing and burn-in test.
● Automatic Testing Sector: Can be integrated in automatic testing system to test electricity parameters, and to supply power to the products under testing.
● Medical Field:Used for medical device testing or it being integrated in medical equipment.
● Communication Sector: Used for the tests of communication power supply and electronic devices.
● 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.
●  Aerospace Sector: Used for aviation electronic products testing and power supply.

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.

Model	SP20VDC600W	SP20VDC1000W	SP20VDC1200W
response(voltage rise time)	≤10ms
response(voltage drop time)	≤150ms(No load)	≤150ms(No load)	≤150ms(No load)
response(voltage drop time)	≤20ms(Full load)	≤15ms(Full load)	≤12ms(Full load)

(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.
