The ABB NTA16-A supplies regulated power to every module in your ABB rack. When it fails, the entire rack goes dark. Capacitor aging is the primary failure mechanism — accelerated by temperature. A supply at 50°C fails years before one at 25°C. Product Type: Medium-Voltage Vacuum Circuit Breaker. Product Number: NTA16-A. Origin: Switzerland.
We test on a live chassis under load: all rails verified, ripple measured, protection circuits checked. 48h burn-in at 55°C. Printed test report. Genuine ABB. 12-month warranty. Ships within 24h.
What testing is performed?
Visual inspection, live-chassis power-up under nominal and peak load, output voltage regulation, ripple and noise measurement, protection circuit verification, 48h burn-in at 55°C. All values documented in printed test report.
Should I keep a spare?
Yes. A spare costs under $2,000. One unplanned rack outage can exceed $10,000/hour. If your chassis supports dual supplies, install both for redundancy.
Is my power supply failing?
Symptoms: module runs hotter than normal, output voltage drifts low, ripple noise on analog signals, intermittent resets, or visible capacitor bulging. Proactive replacement during a maintenance window avoids emergency shutdown.
Compatible Parts — Same System
These modules share the same system family as the NTA16-A. Commonly ordered together for complete rack builds or spare parts kits.
