Defence and strategic installations demand power backup that simply does not fail — under heat, dust, voltage extremes, and continuous duty. Specification here is about proven reliability, rugged operation, clean isolated power, and dependable indigenous supply with full certification and documentation.

Reliability Is the Whole Point

Command centres, communication systems, radar and surveillance electronics, and control infrastructure are mission-critical loads. They require a true double-conversion online UPS with zero transfer time and complete isolation from input disturbances — the load never sees a sag, surge, or transfer event. Output is held at a tightly regulated true sinewave with harmonic distortion under 3%.

Rugged, Continuous-Duty Operation

Strategic sites are often in harsh locations. Paradyne's online range operates across 0-50°C and up to 85% non-condensing humidity, tolerates 110% overload for 10 minutes, and accepts a wide input window for unstable feeders — with generator compatibility for extended autonomy. An inbuilt isolation transformer (see isolation transformer benefits) adds galvanic separation and protection against common-mode disturbances.

Indigenous Supply and Certification

For strategic procurement, indigenous (Make-in-India) manufacturing, assured spares, and certification matter as much as the specification. Demand BIS certification under IS-16242, NABL-backed test reports, and a manufacturer that can support the equipment over its full service life. The underlying performance framework is IEC 62040.

Redundancy

Where downtime is unacceptable, deploy N+1 redundancy with a static transfer switch for maintenance without load interruption, and size battery autonomy generously against the response capability at the site.

What to Specify

• Online double conversion, zero transfer, isolation transformer.

• Rugged environmental rating and continuous-duty overload capability.

• Wide input tolerance and generator compatibility.

• BIS / IS-16242 certification, NABL reports, indigenous manufacture.

• Redundancy and generous battery autonomy.
