AC80 series programmable test power supply successfully developed

The AC80 series programmable test power supply developed by Shandong Boos successfully passed the laboratory certification on June 25, 2019. The R&D center announced that the AC80 series power supply was successfully developed.

1、 Market demand:

With the expansion of the international market of the household appliance industry, it is necessary to simulate the power grids in different regions to test the authenticity of the products. The test power supply is required to have the functions of three-phase unified regulation, three-phase separate regulation, three-phase single-phase fast conversion, etc. In order to meet the test needs of customers, Boas has set up a project to develop AC80 series test power supply.

2、 Product features

1. This series of products adopt high-frequency power electronic switch conversion technology to generate stable and pure sine wave. It is characterized by high degree of automation, stable performance, complete functions, complete protection functions and simple maintenance.

2. At the same time, the power supply adopts sine wave pulse width modulation (SPWM) technology, which has small waveform distortion, high inverter efficiency, low energy loss, good product quality and green.

3、 Features:

1. AC80 series power supply has three modes: three-phase unified regulation mode, three-phase separate regulation mode and three-phase parallel connection mode. (Note: three-phase unified regulation mode: that is, normal three-phase power supply with three-phase simultaneous frequency regulation and voltage regulation; three-phase separate regulation mode: three-phase output is independent loop independent frequency regulation and voltage regulation without mutual interference. Three phase parallel connection mode: three-phase output in parallel is single-phase output with one key conversion.)

2. AC80 series power supply adopts touch screen for operation, which is simple, convenient and beautiful in appearance. The switch between local control and remote control can be realized. The remote digital control function can realize the setting function control of output voltage and frequency, data reading and other data exchange functions. Standard interfaces and communication protocols of R232, R485 or Ethernet can be provided.

3. AC80 series power supply has step function. Through the built-in step function of the machine, step voltage, step frequency and step duration can be set to simulate various power step conditions. It is suitable for simulating power grid disturbance or power switch test items. Because AC80 series has excellent reaction speed, step change of voltage or frequency can be completed in a single cycle.

4. AC80 series power supply has a slow rise/slow drop function. Through the built-in slow rise/slow drop function of the machine, the unit slow rise/slow drop time, unit slow rise/slow drop voltage and unit slow rise/slow drop frequency can be set to simulate various power supply slow rise or slow drop conditions. In addition, the power supply can adjust the climbing speed of voltage or frequency through the ramp function, so as to effectively reduce the surge current generated when the motor or compressor starts.

5. AC80 series power supply has wireless monitoring function: data communication is carried out according to specific protocol through serial port, network port and other interfaces, and these communication data are bridged to the server end by the switching device in a wireless and transparent way to achieve terminal monitoring of the equipment. According to the on-site environment, you can choose the corresponding transfer equipment: for places with broadband networks, you can choose the network port or wireless Wifi transfer equipment to directly connect to the server; For unattended remote areas, you can use a GPRS DTU transfer device to connect to the server after inserting a mobile phone card.
