Frequently Asked Questions
Power Protection Solutions
What is an On-Line Series UPS and why do I need it?
On-Line Series UPS provides total power protection with zero switchover time for mission-critical loads like network workstations, telecom equipment, medical diagnostics, CNC tools, and 3D printers. Available from 1KVA single phase to 150KVA three phase, it ensures uninterrupted operation during outages.
How do PNS Inverters differ from regular inverters?
PNS Inverters deliver high-efficiency pure sine wave power with micro-controller technology, silent operation, and <2ms changeover. Ranging from 500VA to 50KVA, they support lighting, computers, and high surge loads with short circuit protection and Normal/UPS mode selector.
What makes Solar Hybrid UPS Systems special?
These systems charge batteries at optimum solar current and automatically switch between solar, battery, and grid for maximum electricity savings. Capacities from 1KVA single phase to 50KVA three phase suit residential and commercial hybrid applications.
When would I use Static Frequency Converters?
They convert 50Hz/230V input to 60Hz or 400Hz output for imported machinery (e.g., from USA) and aviation equipment, with customizable configurations for precise voltage/frequency needs.
How does PNS Lift/Elevator UPS work?
Designed for 3-6 landing lifts, it supports 40-100 operations during outages using micro-controller tech and heavy-duty batteries. Features automatic startup, manual bypass, low maintenance, and eco-friendly design for apartments, villas, and offices.
What do Servo Controlled Voltage Stabilizers protect against?
They maintain stable voltage (3KVA-3000KVA three phase/1000KVA single phase) against fluctuations that damage equipment. Air/oil cooled with protections like under/over voltage trips, overload (CT-based >110% with delay), short circuit, single phasing, phase reversal, manual bypass, and emergency stop.
Solar PV Solutions
What are the main types of Solar PV Solutions offered?
Portfolio includes Grid Tied PV Power Plants, Off-grid Installations, Solar Water Pumping, Rooftop Solar, and solar panels/components supply, optimized for India’s 300+ sunny days with focus on ROI and low maintenance.
How does a Grid Tied PV Power Plant function?
DC from solar panels converts to AC via power conditioning unit, powering building loads (lights, fans, appliances) with excess fed to grid on net/gross metering. Draws from grid if solar is insufficient (e.g., cloudy days).
What are Off-grid Solar Installations best for?
Standalone systems with battery storage for remote areas without grid access. Custom-sized/design based on needs, fully implemented by PNS professionals.
How do Solar Water Pumping Solutions operate?
Solar panels (series/parallel) power VFD converting DC to AC for pumps, ideal for irrigation, drinking water, livestock, and landscaping with minimal costs and high eco-impact.
