Frequently Asked Questions (Technical & Procurement FAQ)

In-depth answers to common engineering, customization, and factory procurement queries.

What is the difference between an Automatic Voltage Regulator (AVR) and a Programmable AC Power Source?
An Automatic Voltage Regulator (AVR) is designed to dynamically stabilize fluctuating main grid voltages to a fixed target voltage (e.g., 380V ±1%) to protect downstream equipment. In contrast, a Programmable AC Power Source can actively generate variable voltages (0-300V+), frequencies (45Hz-400Hz), and custom waveform distortions to test device behavior under varied grid conditions.
How does bi-directional power technology benefit EV battery testing?
Bi-directional power supplies can act as both a programmable DC source (charging the battery) and a regenerative DC electronic load (discharging the battery). During discharge, up to 95% of the electric energy is fed back into the facility's local AC grid, significantly reducing electricity consumption and heat generation.
Can Shenzhen Sophpower customize power supply parameters according to OEM specifications?
Yes. Sophpower specializes in tailored power solutions. Engineers can customize voltage outputs up to 1000V+, currents up to 1000A+, specific cabinet physical dimensions, custom communication protocols (SCPI, CAN, RS485), and specialized water or forced-air cooling designs.
What automated control interfaces are supported for industrial remote control?
Sophpower's programmable DC and AC power units support standard RS232, RS485, CANbus, USB, and LAN (Ethernet) interfaces using SCPI (Standard Commands for Programmable Instruments) or Modbus protocols, allowing seamless integration with LabVIEW, PLC SCADA, and Python automation scripts.
What quality inspection procedures are implemented before factory dispatch?
Every power control unit undergoes a multi-step quality verification process: component-level LCR testing, automated reflow inspection, full-load thermal imaging, oscilloscope harmonic analysis, 100% full-power burn-in testing, and high-voltage dielectric insulation safety testing.
