High-Quality MCHF Series High Frequency UPS Power Supply Manufacturer, Companies

The MCHF series (1-10kVA) adopts DSP digital control technology. On the basis of solving 9 major power problems (mains power failure, voltage sag, surge, undervoltage, overvoltage, electronic interference, frequency fluctuation, transient change, harmonic distortion, etc.), it further improves the adaptability and reliability of the product, providing foolproof protection for user equipment and the UPS itself. The MCHF series 1-10k is mainly applied to department-level servers, small local area networks, workstations, industrial control computers, small medical equipment, and other small precision electronic instruments.

Product Description

Protection Features

Power-on Self-Diagnosis: Detects hidden faults of the UPS proactively to eliminate potential hazards before system startup.

Comprehensive Safeguards: Integrates AC input overvoltage/undervoltage, output overload/short-circuit, inverter overheat, battery undervoltage warning, and overcharge protections.

Uninterrupted Bypass: Automatically transitions to bypass mode with real-time acoustic alarms during output overload or hardware failure without dropping load power.

Line Phase Verification: Built-in live/neutral line polarity check prevents reverse connection hazards on mains input wiring.

Cold Start Capability: Equipped with a powerful DC start function allowing equipment activation directly from battery storage without mains presence.

Strong Environmental Adaptability

Wide Input Voltage Range: Operates seamlessly between 115VAC and 300VAC, drastically reducing battery discharge frequency in erratic power environments.

Low Voltage Capability at Half Load: Input voltage can drop down to 115V at 50% load without switching to battery power, preserving energy reserves.

Generator Compatibility: Broad 46Hz–64Hz input frequency response adapts easily to fluctuations from fuel-powered generators.

Frequently Asked Questions (FAQ)

What is the transfer time from AC mode to battery mode?

The transfer time between AC mode and battery mode is zero (0 ms), delivering continuous, uninterrupted pure sinewave power to protect sensitive equipment.

Can this UPS system run reliably with a fuel generator?

Yes. With an ultra-wide input frequency window of 46Hz to 64Hz, the system maintains stable synchronization and smooth operation with various fuel generators.

What happens during mains power fluctuations or low voltage?

The unit accepts an input voltage range of 110–300 VAC. At half load, it operates down to 115 VAC without draining battery power, preserving capacity for true outages.

What is the difference between Standard Models and Long-run Models?

Standard models include internal batteries designed for typical backup intervals. Long-run models feature an enhanced 4.0A charger and configurable external battery setups for long-duration runtime.

What monitoring and communication options are supported?

It supports RS-232 / Smart RS-232 ports along with optional USB, AS400, and SNMP cards. Power management is compatible with Windows, Linux, Unix, and Mac platforms via local software or web browsers.

How does the UPS alert users in case of faults or abnormal conditions?

The unit provides multi-tier acoustic alarms: battery mode (beeps every 4 seconds), low battery (beeps every second), overload (twice per second), and continuous beeping for fault states, accompanied by real-time status readings on the panel.
