MGE Pulsar STS 16 Source Transfer Switch (16A, 208-240V)

The MGE Pulsar STS 16 (Source Transfer Switch) is a compact, highly reliable 1U rack-mountable device designed to offer power supply redundancy for single-corded sensitive equipment. The Pulsar STS 16 is designed to connect two independent AC power sources and automatically and smoothly switches important loads to an alternate supply line when the primary source fails or goes out of voltage tolerances.

Whether in a typical IT data center, on an automated manufacturing floor or in a demanding maritime bridge console, this machine guarantees zero downtime for your vital automation networks and navigation monitors. Designed with a break-before-make feature to minimize dangerous source co-mingling, it creates an ultra-fast transfer speed of less than 6 milliseconds, allowing your systems to stay functioning without a reset.

Model Details

• Model: Pulsar STS 16
• Manufacturer Part Number (MPN): 66028
• Alternative Part Numbers / Cross-References: HP QV559A, EATS16, Eaton Pulsar STS 16, PULSAR-STS-16

Features

1. Ultra-Fast Transfer Speed: Instant, automatic transfer between independent AC sources in less than 6ms, below the drop-out threshold of sensitive equipment switch-mode power supply.
2. Break-Before-Make (BBM) Design: The two inputs are electrically isolated and do not interact, therefore there is no possibility of short circuits or phase-to-phase faults between independent upstream sources.
3. Comprehensive Mimic Diagram: The front-panel user interface has an easy LED mimic diagram, allowing operators to view source availability, preferred path, and output load issues at a glance.
4. Integrated Dry-Contact Communications: The unit includes a ‘STS COM’ Sub-D 9 pin relay port for remote monitoring, providing clean signals for primary source failure, backup power tracking and internal switch health.
5. Dual Thermal Cutouts Native dedicated overcurrent protection included into the output receptacles to ensure downstream localized faults isolate safely without risk of entire system functioning.
