Optimized Solution for Compact Wall-Mounted DC Power Systems

Product Highlights

Perfect Fit for Wall-Mounted Cabinets: Compact dimensions (260*179*109mm) with fanless design, ideal for space-constrained wall-mounted power systems. Eliminates need for large ventilation ducts.
Maintenance-Free & Silent Operation: Natural convection cooling ensures zero noise operation, perfect for indoor substations or office environments, while preventing dust accumulation.
Industrial "Four Remote" Functions: Standard RS-485 interface for seamless SCADA integration. Monitor voltage/current, receive fault signals, and control output remotely for unattended operations.
High Reliability & Efficiency: Resonant Voltage Mode Control technology achieves up to 95% efficiency. Stable 230VDC output in harsh industrial environments (-10℃ to +40℃).
Plug-and-Play Protection: Comprehensive protection including Foldback Short-Circuit Protection, Over-Temperature, and Output Over-Voltage lockout.

Product Description

The TONHE TH230D05ZZ-3 is a high-efficiency, fanless 5A intelligent rectifier module engineered specifically for 220VDC electrical control applications. This module provides the perfect balance between power density and physical size for modern power systems.

Why Choose TH230D05ZZ-3 for Wall-Mounted Systems?

In wall-mounted DC power systems, space and noise are primary concerns. The TH230D05ZZ-3 fits perfectly into small wall cabinets without requiring excessive clearance for forced-air ventilation. The fanless design relies on natural convection, making it an ideal "fit-and-forget" solution for indoor substations or control rooms.

Smart Management for Unattended Operation

Equipped with standard RS-485 communication port, this module supports "Four Remote" functions. System operators can monitor power supply health in real-time from central dispatch centers, remotely adjust output voltage (190V-300V range), or set current limits (10%-100%) without physical site visits.

Fail-Safe Protection

Safety is paramount in power distribution. The module utilizes "Foldback" short-circuit protection mechanism. During short circuit events, it automatically reduces output current to safe levels (below 15% of rated current). Normal operation resumes automatically once faults are cleared, minimizing downtime.

	Ripple Coefficient		≤0.2%
	Load Level		Class I (Continuous operation at 100% rated output current)
	Automatic Current Limiting		When output current exceeds the set current limit value, the charger switches to constant current output and the current will not increase.
	Output Overvoltage Protection		Automatically stops output when output voltage exceeds 320±5 VDC to prevent equipment damage.
	Output Short Circuit Protection		The module self-protects during an output short circuit to prevent damage; it can automatically resume normal operation once the fault is cleared.
	Note		Voltage regulation accuracy does not include the effect of the built-in isolation diode.
