Product Details
| Brand Name | Tonghe | Model Number | TH220D03ZZ-3 |
Product Description
Module model: TH220D03ZZ-3
Main features of the module:
Adopting full range soft switching technology, high efficiency, low no-load power consumption, and small size.
The AC input has a built-in safety compliant fuse.
Measures to achieve hot swapping. Other similar products without built-in diodes require users to add additional diode heat sinks to the DC screen, resulting in cumbersome wiring.
Using a "three-phase passive power factor correction circuit", the input has no neutral line, and the power factor can reach 0.94.
Isolated and autonomous current sharing is adopted, and the uneven current degree of parallel operation is ＜ ± 3%, which can ensure good parallel operation of more than 20 modules.
The module has an RS-485 interface for easy access to automation systems for communication** Output overvoltage protection: Built-in overvoltage protection circuit, the module automatically locks up after overvoltage occurs, the module fault indicator lights up, and the faulty module automatically exits operation without affecting the entire system. 160V ± 5% * * Output current limiting protection: The output current of each module is limited to 1.05 times the rated output current.
Short circuit protection: The retractable droop current limiting method is adopted. When the output short circuit occurs, the module momentarily pulls the output voltage down to zero, limiting the short circuit current to less than 15% of the rated output current. The module can operate in a short circuit state for a long time without damage. After troubleshooting, the module can automatically resume operation.
Module parallel protection: There is a parallel protection circuit inside the module, which automatically exits the system in case of a fault, without affecting the normal operation of other modules (* * Over temperature protection: The module automatically shuts down for protection when it detects that the radiator temperature exceeds about 85 ℃, and the module automatically starts when the temperature decreases.
