DC Rectifier Module & Industrial Power Supply TH48D30NZ-S-2

Product Overview

The TH48D30NZ-S-2 is a 1U rack-mount high-frequency switching rectifier module (DC power supply) from TONHE, engineered for communications and industrial integrated power systems. It delivers a stable 48V DC output at up to 30A (1750W maximum) from a compact 1U chassis, with dual input — AC 176–264V or DC 176–286V — for maximum deployment flexibility. Conversion efficiency of ≥94% and standby power of ≤5W keep long-term electricity and cooling costs low. Hot-swap capability, parallel current sharing (±5%) and RS485 remote monitoring make it easy to scale capacity and maintain the system without downtime. Certified CE and ISO9001.

Key Specifications

Key Benefits
1. 1U high power density – 1750W in a 248 × 110.2 × 44.7 mm 1U module: more power per rack unit, ideal for space-constrained cabinets and capacity upgrades.
2. Dual AC/DC input – Runs on 176–264VAC or 176–286VDC, so one module fits multiple mains and backup environments — fewer SKUs, simpler spares.
3. High efficiency, low standby loss – ≥94% conversion efficiency and ≤5W standby power cut electricity and cooling costs over long-term operation.
4. Precise regulation, reliable paralleling – ±0.5% voltage regulation with ±5% current-sharing imbalance for stable output when modules run in parallel.
5. Multi-protection, maintenance without downtime – Constant-current limiting, short-circuit protection (no shutdown), over-temperature protection with auto-restart; hot-swap replacement while the system stays online.
6. Remote monitoring – RS485 interface integrates with your power monitoring system for remote supervision and control, reducing site visits.

Applications
- Telecom infrastructure – 4G/5G base stations, transmission and data equipment, core network rooms (–48V DC power).
- Integrated power systems – DC backup power, AC/DC integrated power cabinets (telecom power plants, data-center UPS companion).
- Data centers & network racks – High-density 48V DC power distribution and equipment cabinets.
- Industrial & general high-density supply – Any equipment requiring stable 48V output at high power density.

FAQ
Q1. What is the output capability of the TH48D30NZ-S-2?
Rated DC 48V / 30A output with a 1750W maximum; output voltage is adjustable from 40–60VDC to suit float and equalize charging settings.

Q2. What input does it accept — AC, DC, or both?
Both. Dual input: AC 176–264V (rated 220V) or DC 176–286V, so it adapts to different mains and backup power environments.

Q3. Can multiple modules be paralleled for more capacity?
Yes. Modules support parallel current sharing with ≤±5% imbalance, so you can build larger 48V power systems by adding modules as capacity grows.

Q4. What are the operating temperature and cooling requirements?
Operating temperature -10°C to +40°C, storage -40°C to +60°C; forced-air (fan) cooling with intelligent derating, audible noise ≤55dB.

Q5. What protections are included? Does it support hot-swap and remote monitoring?
Constant-current limiting, short-circuit protection (output does not shut down) and over-temperature protection with automatic restart. The module supports hot-swap and RS485 remote monitoring, so it can be replaced without taking the system offline.
