Export Case
We have supplied TH24D75NZ-S 24V telecom rectifier modules for telecom operator projects in Southeast Asia. The modules were deployed in rural communication base station outdoor power shelters, adopting N+1 redundant configuration. The power system runs stably under high temperature and unstable local grid conditions. Customer achieved reliable 24V DC power supply for radio equipment, and greatly reduced site maintenance frequency. Up to now, the system has maintained low failure rate and won repeat orders from local system integrator.
FAQ
Q1: Can TH24D75NZ-S work in parallel with multiple modules?
A: Yes. It supports multi-module parallel operation with automatic current sharing. N+1 redundant configuration is recommended for telecom backup power system.
Q2: Does this rectifier support hot swap?
A: Yes. Hot-swap design, you can plug/unplug the module without shutting down the whole power system for easy maintenance.
Q3: What communication protocol does RS485 port use?
A: Standard Modbus-RTU protocol, compatible with most telecom monitoring units, support remote read voltage, current, temperature and alarm status.
Q4: What certificates are available for export?
A: CE, RoHS, IEC telecom power standard test report. We can assist to apply for other regional certificates upon request.
Q5: What is the warranty period?
A: Standard 3-year warranty. We provide remote technical support during warranty period; spare parts solution will be offered for faulty units.
