When Power Fails, Business Continues: Prostar PER Series Rack UPS Protects IT Infrastructure with 0ms Transfer and PF 1.0

IT Infrastructure · Enterprise — August 15, 2026 – Prostar PER Series rack mount online UPS delivers 1-10kVA power protection for servers, networks and workstations, ensuring 0ms transfer and PF 1.0 full power factor for business-critical IT systems. With 110-300V ultra-wide input range and up to 95.5% ECO efficiency, the PER Series keeps business operations running when the grid fails.

Why IT Infrastructure Needs Zero-Downtime Power Protection

Modern enterprises depend on continuous power for their IT infrastructure. Servers, network switches, workstations, and storage systems — all require stable, clean power to function reliably.

A single power outage or voltage sag can cause:

Server downtime — Interrupted services, lost transactions, data corruption
Network failure — Disrupted communications, remote work interruptions
Workstation shutdowns — Lost productivity, unsaved work, delayed deadlines
System crashes — Operating system corruption, application failures

The Prostar PER Series eliminates these risks by providing uninterrupted power protection for every critical IT asset.

How Prostar PER Series Protects IT Infrastructure

The Prostar PER Series is a 1-10kVA rack mount online UPS, 1:1, with output power factor 1.0 and voltage options 208/220/230/240VAC. Its 2U form factor fits standard 19-inch racks.

Key Specifications:

Capacity: 1-10kVA / 1-10kW
Power Factor: 1.0
Input Voltage Range: 110-300VAC
Transfer Time: 0ms
ECO Mode Efficiency: Up to 95.5%
Form Factor: 2U Rack Mount

1. 0ms Transfer — Zero Business Interruption

The PER Series uses true online double-conversion architecture. When the grid fails, transfer to battery mode occurs in 0 milliseconds. Servers stay online. Networks remain connected. Workstations never reboot.

2. PF 1.0 Full Power Factor — 25% More Load Capacity

Output power factor of 1.0 means every kVA is real usable power — 25% more load capacity than traditional 0.8 PF systems. For high-density IT environments, this provides maximum efficiency and reserve capacity for future expansion.

3. DSP Full Digital Control — Intelligent Protection

The PER Series utilizes advanced DSP digital control technology, delivering high performance and system reliability. Microprocessor control ensures optimal protection for critical IT equipment.

Technical Comparison: Prostar PER Series vs Standard UPS for IT Infrastructure

Parameter	Prostar PER Series	Standard UPS	IT Advantage
Transfer Time	0ms	2-10ms	Zero server interruption
Output Power Factor	1.0	0.8	25% more usable capacity for IT loads
Input Voltage Range	110-300VAC	170-270VAC	Stable operation in any grid condition
ECO Mode Efficiency	95.5%	~90%	Lower operating costs for 24/7 IT
Cold Start	Yes	Limited	Emergency power when grid is down
SNMP Remote Management	Yes (optional)	Varies	Integrated network monitoring

Why 110-300V Wide Input Range Matters for IT Infrastructure

The PER Series operates across an ultra-wide input voltage range of 110-300VAC. This provides three critical benefits for enterprise IT:

Extended battery life — Fewer charge/discharge cycles prolong battery lifespan
Uninterrupted operation — Stable output even during severe voltage fluctuations
Generator compatibility — Seamless operation with standby generators during extended outages

«In today's digital enterprise, power outages are not just an inconvenience — they are a business risk. The Prostar PER Series provides the zero-downtime protection that modern IT infrastructure requires. When power fails, business continues.» — Prostar Engineering Team

Frequently Asked Questions

Why does IT infrastructure need 0ms transfer time in a UPS?

Servers and network equipment cannot tolerate even milliseconds of power interruption. A 2-10ms transfer time can cause server reboots, data corruption, or network downtime. The PER Series 0ms transfer ensures complete continuity for business-critical IT operations.

What UPS capacity is recommended for server rooms?

Capacity varies by server count and load type. The PER Series covers 1-10kVA, from small network cabinets to larger server rooms. A site-specific load calculation is recommended for accurate sizing.

What IT equipment does the PER Series protect?

The Prostar PER Series protects servers, network switches, routers, firewalls, storage systems, workstations, and other business-critical IT equipment in server rooms, data centers, and network cabinets.

Is ECO mode safe for IT infrastructure protection?

Yes. The PER Series ECO mode delivers up to 95.5% efficiency while maintaining full protection. When grid quality is stable, the UPS operates in bypass mode for maximum energy savings, automatically switching to double-conversion mode instantly if grid quality degrades.

Can the PER Series be remotely managed?

Yes. The PER Series features an optional SNMP extension slot for network management. It also includes standard USB and RS232 communication interfaces for local monitoring.

Conclusion

Your business never stops. Neither should your power. Prostar PER Series rack mount online UPS — with 0ms transfer, PF 1.0 full power factor, DSP full digital control, and 110-300V wide input — ensures IT infrastructure remains operational even when the grid fails.
