Foldback short-circuit protection and over-temperature protection safeguard both module and connected equipment
Detailed Product Description
The TONHE TH220D03ZZ-220AC is a high-efficiency, fanless power module engineered specifically for 220VDC electrical control applications. With a rated output of 3A, this module serves as the optimal "Power Hub for Control Circuits" in wall-mounted power systems, ring main units (RMUs), and industrial control panels where space is at a premium.
Silent & Dust-Proof Operation
Unlike traditional forced-air cooled modules, the TH220D03ZZ-220AC operates completely silently. The fanless design eliminates the most common point of failure in power supplies while preventing dust intake that can cause short circuits in sensitive electronics.
Smart Management Capabilities
Equipped with standard RS-485 communication port, this module supports "Four Remote" functions, allowing system operators to monitor power supply health in real-time and remotely adjust output voltage (190V-300V range) or current limits without physical site visits.
Fail-Safe Protection System
Safety is paramount in power distribution. The module utilizes "Foldback" short-circuit protection that automatically reduces output current to safe levels during faults and resumes normal operation once cleared, minimizing downtime.
