MS Series 50KVA-720KVA Modular Online UPS

·High Reliability Design

Ultra-wide input voltage range 138~485Vac(phase voltage 80~280Vac), no derating is used above 305Vac

·Energy Saving And Environmental Protection

High input PF value,up to 0.99,adopts three-level topology, and the efficiency of the whole machine is as high as 96.5%

·Parallel Redundancy Function

Parallel directly,6 units can be connected in parallel, supporting parallel sharing of battery packs

·Flexible Battery Configuration Scheme

The number of battery cells is 30~50,and the single machine has large capacity charging power to meet the backup demand of long delay.

·Super Load Capacity

The output power factor is 0.9,can carry 100%unbalanced load, the load adaptability is strong,can carry the pure inductive load and the capacity load close to full load

·Compatible With Generator Operation

The Power Walk In function reduces the inrush current of system startup and reduces the demand for generator capacity of the parallel system

·LBS Synchronization Function

With LBS synchronization function,realize the synchronization of two independent UPS systems,and provide system reliability

·Intelligent Management Function

Support RS485,SNMP,dry contact,CAN interface

Efficiency hits 96.5% thanks to a three-level topology, and input power factor is up to 0.99. That translates to less waste heat and lower operating costs, which matters when you’re running hundreds of kilowatts around the clock.

Parallel redundancy is straightforward—you can connect up to six units directly, no extra cabinets or complex wiring. They can even share a common battery bank, which simplifies installation and cuts down on battery costs.

Battery configuration is unusually flexible. You can set the number of cells anywhere from 30 to 50, and the built-in charger has enough capacity to handle long runtime requirements without needing external chargers.

Load handling is solid. Output power factor is 0.9, and it can carry 100% unbalanced loads without complaining. If you’re running pure inductive loads or near full-capacity loads, it handles them—no derating games.

For sites running on generators, there’s a Power Walk‑In function. It gradually ramps up the load when the system starts, so you don’t get a massive inrush current that trips a generator or forces you to oversize it.

If you need even higher redundancy across separate systems, the LBS (Load Bus Synchronization) function keeps two independent UPS systems synchronized. That lets you build a distributed architecture where multiple UPS units support the same critical bus.

Communication options cover RS485, SNMP, dry contacts, and CAN interface, so it fits into most building management or data center monitoring setups without adapters.

The modular design also simplifies maintenance—if a power module needs attention, you swap it out without taking the whole system offline. No downtime, no juggling loads to a bypass.

In short, it’s built for environments where uptime is critical but the future is uncertain. You scale it, you protect it, and you don’t lock yourself into a fixed capacity from day one.
