SWD three-phase insingle-phase out UPS parameter table

Understanding the SWD Three-Phase In/Single-Phase Out UPS System

The SWD series UPS is designed for scenarios where three-phase power input needs to be converted to stable single-phase output. This configuration is particularly useful in industrial settings where sensitive single-phase equipment must operate reliably despite fluctuating three-phase power sources. As a factory-direct manufacturer with 20 years of experience, China Hongye Electric has optimized these systems for both performance and cost-efficiency.

Key Parameters in the SWD UPS Specification Table

When evaluating the parameter table, focus on these critical specifications:

• Input voltage range: Typically 380V±20% for three-phase
• Output voltage: Stable 220V single-phase with ≤±1% regulation
• Capacity options: Ranging from 1KVA to 30KVA for different load requirements
• Transfer time: ≤4ms to ensure uninterrupted power
• Efficiency: >90% in online mode for energy savings

How to Select the Right SWD UPS Model

Choosing the appropriate UPS involves more than just matching power ratings. China Hongye Electric's engineers recommend considering:

What Factors Affect UPS Selection?

First, calculate your total load requirements including startup surges. For specialized applications like medical imaging or CNC equipment, we often recommend oversizing by 20-30%. Second, evaluate your runtime needs - our SWD series supports external battery packs for extended backup. Third, consider environmental factors; our units with IP21 protection are suitable for most indoor industrial environments.

China Hongye Electric provides free engineering support for proper sizing. With our complete in-house production from silicon steel cores to final assembly, we can also accommodate custom voltage or capacity requirements that standard models don't cover.

Installation and Maintenance Best Practices

Proper installation significantly impacts UPS performance and lifespan. Here are key considerations:

Common Installation Mistakes to Avoid

• Inadequate ventilation space around the unit
• Improper torque on terminal connections
• Grounding the neutral line incorrectly
• Overlooking input voltage compatibility checks

All China Hongye Electric UPS systems undergo rigorous full-load testing before shipment, including:

1. High-potential withstand testing
2. Temperature rise verification
3. Output waveform analysis
4. Automatic transfer simulation

Why Choose Factory-Direct UPS Solutions?

As a manufacturer with our own production facilities, China Hongye Electric offers distinct advantages for SWD UPS procurement:

• Cost savings: Eliminating middlemen means better pricing
• Quality control: Direct oversight of every production stage
• Customization: Ability to modify standard designs for special needs

For complex power scenarios, our engineers can develop tailored solutions combining SWD UPS with other power conditioning equipment from our nine product series. This integrated approach often proves more reliable than piecing together components from multiple suppliers.

With 20 years in power equipment manufacturing and over 10,000 industrial clients served, China Hongye Electric stands behind every SWD UPS with a three-year warranty and lifetime technical support.
