Natural convection cooling eliminates fan noise entirely, ideal for noise-sensitive environments and prevents dust accumulation.
Industrial "Four Remote" Functions
Standard RS-485 interface for seamless system integration with telemetry, tele-signaling, and tele-control capabilities.
Robust Protection Suite
Foldback short-circuit protection, output over-voltage lockout, and over-temperature protection safeguard critical loads.
Plug-and-Play Parallel Operation
Supports N+1 redundancy with current sharing error < ±3% when paralleled with up to 20+ units.
Product Description
TONHE TH230D10ZZ-220AC 10A Intelligent Rectifier Module
The Powerhouse for Compact 220VDC Systems
The TONHE TH230D10ZZ-220AC is a high-efficiency, fanless power module engineered specifically for 220VDC electrical control applications. With a rated output of 10A, this module delivers more power in the same space.
Why Choose the 10A Fanless Module?
In compact DC power systems, balancing power output and physical size is critical. The TH230D10ZZ-220AC fits into standard wall-mounted enclosures without requiring ventilation clearance, offering double the power (3kW) of 5A versions while maintaining identical dimensions.
Smart Management for Unattended Sites
Equipped with standard RS-485 communication port, this module supports "Four Remote" functions, allowing operators to monitor power supply health in real-time from central dispatch centers and remotely adjust output voltage (190V-300V range) or current limits.
Fail-Safe Protection
The module utilizes "Foldback" short-circuit protection that automatically reduces output current to safe levels during faults and automatically resumes normal operation once faults are cleared, minimizing downtime.
