TOPAZ S4

The Next Generation in AC Telecom Power

MGE's Topaz S4 N+1 scalable DC to AC inverter is the latest addition to the Topaz inverter line recognized as the industry standard for critical AC power by many of the world's leading telecom companies.

SCALABILITY: Scalable 3.5 kVA inverter power modules can be stacked in a N+1 redundant configuration (paralleled for redundancy or capacity) up to 21 kVA.

OPTIMUM AVAIALABILITY: All modules are packaged into a "hot swap" receiver cabinet with an integrated maintenance bypass allowing rapid and safe exchange of any component without interruption to the critical load.

NEBS STANDARDS: The S4 is one of the only inverters designed to meet NEBS standards assuring compatibility with all devices in a telecom environment.

RELIABILITY: Redundant microcontrollers feed control signals to each inverter along a dedicated and isolated control line resulting in an MTBF greater than 99 years.

TELECOM GRADE FILTERING: High-end power filters limit ripple current on the DC bus to a negligible 32 dB, preventing micro-cycling of the battery. EMI filters regulate conducted and radiated interference that could potentially create noise disturbances. This high grade filtering is unique to the S4 making it the choice for telecom environments.

The S4 is available with the following optional accessories, all of which can be factory installed on an open frame relay rack, providing a ready to install inverter system.
Maintenance Bypass: Safely and seamlessly transfers the output to an alternate AC source (utility power or protected AC power from another inverter or UPS system) allowing the inverter to be shut-down or removed without interrupting power to the critical loads. The Maintenance Bypass assembly is factory wired to the inverter module when ordered as a system.

AC Distribution Panel: The AC distribution panel accommodates 20 single pole breakers and is available in 120 and 240 VAC versions. 10 x two pole breakers can be used if distribution alarm monitoring is required.

Web Based Monitoring: The Falcon monitoring system (1.75" high rack mounted) provides inverter, maintenance bypass and AC distribution status and alarms over a closed network or via the Internet serving up web pages that can be viewed with a standard browser or via SNMP or dial up access. Accessories include environmental monitoring modules and auxiliary inputs to monitor other devices such as leak detection systems, room security or any other dry contact status points.

Open Frame Relay Rack: All components can be mounted on an industry standard open frame relay rack with the entire inverter plant certified for zone 4 seismic installations.

Conduit Junction Boxes: (not required when mainstream bypass is used) Larger inverter modules such as the 14 kVA through 21 kVA require substantial cable gauges. The conduit junction box is factory mounted to the back of the inverter module, easing conduit landing requirements and simplifying installation of rear or side mounted cable entry systems.
