Product Introduction
The five-in-one energy storage controller integrates an HV PDU module, an AC/AC module, and a DC/DC module. Its main functions are:
1. HV PDU Module: Distributes the 220Vac input power to the AC-DC module and the heating PTC, and performs EMC treatment on the AC/AC circuit branch.
2. AC/AC Module: Rectifies and boosts the AC 220Vac to 380Vdc DC, providing power to the DC/DC and DC/AC converters and driving the compressor.
3. DC/DC Module: Converts 380Vdc DC power to 24Vdc DC power, provides split-output channels, and features control functionality.
4. Control power module: Converts the 220Vac input power to a 24Vdc output for control power supply.
