The PowerHandler Plus is a switchboard system bypass module designed for 3200A to 4000A applications. The unit allows engineers to service paralleled UPS systems without taking critical loads offline. It features draw-out breakers, a small footprint, and a fully rated static switch.
The new model TSS Talon surge suppressor is a bidirectional, parallel-connected device designed for electrical distribution panels or other critical-load applications in facilities that may experience internally generated transients. It is an MOV-based product that is rated 40 kA of 8 × 20μs surge current for each mode of protection and provides L-N and N-G protection.

Battery Charge Controller
The charge control device (CCD-100) is designed to regulate standby battery charging for improved battery performance and lifespan. The device offers temperature-compensated voltage regulation for 12V monobloc batteries, and it does not interfere with post-discharge equalization/recharge cycles.
The Unigy high-rate series of absorbed, VRLA batteries are designed for high-rate UPS systems. The 12V monobloc batteries are housed in reinforced cases constructed of polyproylene or flame-retardant plastic. They also feature absorbed glass-mat construction with Hovosorb® separators, tank-formed plates, and self-sealing vents.

Surge Protection Devices
The PLUGTRAB PT series of DIN-rail mount surge protection devices protects up to four signal lines or two data lines in less than ¾ in. of rail space. The devices divert surge voltage and current away from I/O and data cards. They feature a plug-gable design, an automated testing device, and more than 10 kA of surge current handling capacity.
Ground Resistance Meter
The Sterling 2301 clamp-on ground resistance meter attaches to ground conductors or rods up to 45 × 32 mm with single-hand operation and reads resistance with 0.01 ohm resolution. The meter also measures leakage current and features 99 memory settings, three calibration loops, an audible alarm, and a hard carrying case.

Engine Control System
The Engenius™ engine system manager (ESM™) puts gas compression and distributed generation operators in complete control of their engines, regardless of engine locations. The solid-state device monitors speed, pressure, temperature, and other engine conditions; controls ignition timing, speed governing, and stop/start functions; and provides diagnostic help and fault logging when requested.
Automatic Transfer Switches
The ZTS-MV series of automatic transfer switches includes a NEMA- and ANSI/IEEE-compliant switching system designed to handle loads in the 5kV to 15kV range. The switches include dual electric interlocks, an integrated microprocessor-based control module, power and control module isolation, source availability indication, and a NEMA 1 enclosure with front and rear accessibility.
GE Zenith Controls
The STARSINE™ advanced rotary UPS provides up to 12 sec of batteryless ride-through during power-line disturbances and short-term outages. The unit's induction motor operates in conjunction with a surge limiting line reactor, an electronics control package, a low-speed flywheel, an engine, and a generator clutch. Models' ratings range from 315kVA to 2.2 MVA with nominal input voltages of 480VAC or 4160VAC.
