What communication options are available?

It comes with standard RS232, and optional USB, SNMP network card, dry contacts, and AS400 card for remote monitoring and automatic system shutdown.

Can it operate without mains power?

Yes. It supports cold start, allowing the UPS to power up from the battery alone when no mains supply is available ideal for emergency situations.

Is it compatible with generators?

Yes. It is fully generator-compatible and operates stably on genset power without imposing harmonic burden, making it suitable for off-grid or weak-grid sites.

What is the input power factor?

The input power factor is greater than 0.99 with active PFC, reducing harmonic pollution and improving energy efficiency.

What is the warranty and after-sales support?

As a factory-direct manufacturer, we offer long warranty periods, lifetime maintenance service, and 24-hour response for technical inquiries.

Key features

Zero Transfer Time: True online double-conversion with 0ms switchover keeps loads running during utility failures. Ideal for data centers, server rooms, medical equipment.

Ultra-Wide Input 110-288VAC: Maintains stable output under severe voltage fluctuation and frequency drift (40-70Hz). Perfect for regions with unstable power grids.

Built-in Isolation Transformer: Blocks noise, eliminates ground loops, delivers near-zero neutral-to-ground voltage. Essential for labs, hospitals, precision instruments.

Single/Dual-Phase Output: Configurable to 220/240V single-phase or 120V+120V dual-phase via jumper, compatible with both 220V and 120V markets.

Input PF Greater Than 0.99: Active PFC reduces reactive power loss and harmonics, lowering energy costs and meeting green procurement standards.

Strong Overload Capacity: Sustains 105-125% load for 10min, 125-150% for 60s; handles motor startup surges in CNC machines and compressors.

Generator Compatible: Operates stably on genset supply without harmonic burden, ideal for off-grid construction sites, remote telecom stations, oil fields.

Cold Start Function: Powers up from battery alone with no mains available, critical for emergency response and disaster recovery.

50/60Hz Auto-Sensing: Detects input frequency and converts 50Hz to 60Hz or vice versa without extra hardware. Perfect for mixed-frequency export markets.

Full Communication Suite: RS232 standard with optional SNMP, USB, dry contacts, AS400 for remote monitoring and automatic server shutdown during outages.
