Why Engineers Specify ShieldWatt

Every UPS we manufacture is the product of rigorous engineering discipline — validated against IEC 62040, UL 1778, and real-world operating conditions that simulated tests alone cannot replicate.

1

Reliability Engineered Into Every Component

80,000-hour accelerated life testing, thermal cycling from -25°C to +55°C, and field failure rates consistently below 0.08%.

2

Active PFC with PF > 0.99

Input THD below 3% reduces upstream transformer heating and eliminates reactive power penalties on your utility invoice.

3

Modular Hot-Swap Architecture

Add capacity or replace modules without powering down your load. Mean time to repair under 15 minutes for module-level failures.

4

Multi-Standard Global Compliance

UL 1778, CE (LVD), IEC 62040, CSA, and CCC — one product platform certified for deployment in 55+ countries.

5

ISO 14001 Certified Manufacturing

CO2 emissions per unit reduced by 30% over five years. RoHS compliant across our full product range.

Trusted by Engineers Worldwide

Hear from the facilities managers, electrical engineers, and procurement teams who rely on ShieldWatt power protection every day.

We have been deploying ShieldWatt UPS systems across our data center portfolio for six years. The consistent transfer time performance and responsive field engineering support have made them our preferred supplier for Tier III and Tier IV facilities.
Henrik J. Lindberg
VP of Data Center Infrastructure, NordicCloud Hosting AB
When our primary switchboard failed during a thunderstorm, the ShieldWatt modular UPS kept our entire production line running without a single millisecond of interruption. That level of protection is why we standardized on their platform across all five sites.
Laura M. Petrov
Plant Engineering Manager, Continental Process Industries GmbH
ShieldWatt's engineering team reviewed our hospital power architecture and identified three single points of failure we had overlooked. Their redundant UPS configuration recommendation has given our surgical suites genuine peace of mind.

Frequently Asked Questions

Answers to the technical and commercial questions our engineering team receives most often.

Online double-conversion UPS continuously converts incoming AC power to DC and back to AC, providing complete isolation from grid anomalies with zero transfer time. Line-interactive UPS uses an autotransformer to regulate voltage but switches to battery during outages, resulting in a 2-4 ms transfer time. For mission-critical loads — data centers, medical imaging, precision manufacturing — ShieldWatt recommends online topology exclusively.

UPS sizing starts with a load audit: sum the VA or watt ratings of all connected equipment, apply a derating factor for power factor (typically 0.8-0.9), then add 20-30% headroom for future expansion. For three-phase installations, verify load balancing across phases. ShieldWatt's applications engineering team provides free sizing consultations — submit your single-line diagram via our contact form and we will return a detailed specification within 48 hours.

All ShieldWatt UPS systems are UL 1778 listed, CE marked under the Low Voltage Directive 2014/35/EU, CSA certified, and CCC approved for the Chinese market. Our manufacturing facilities hold ISO 9001:2015 and ISO 14001:2015 certifications, and all products comply with RoHS 2011/65/EU and the ENERGY STAR program where applicable. Complete compliance document packages are available on request.

Standard modular UPS configurations ship within 4-6 weeks from our Gothenburg facility. Custom-engineered systems — including special voltage ratings, extended battery autonomy, or application-specific communication interfaces — typically require 10-14 weeks from design freeze to delivery. Emergency stock programs are available for critical infrastructure projects requiring expedited timelines.

Yes. Our service programs include scheduled preventive maintenance visits (semi-annual or quarterly), battery health monitoring and proactive replacement, firmware updates, and 24/7 remote monitoring via SNMP or Modbus TCP. Service contracts are available in 50+ countries through our network of factory-trained field service engineers. Contact our service desk for a maintenance plan tailored to your installation.
