Power Control Systems

These power control and synchronizing switchgear systems are designed with low- and medium-voltage ratings for single- and multi-unit on-site power generators. In addition to emergency power, system designs may include peak shaving, load curtailment, and utility paralleling for both open transition transfer and live-source closed transition transfer. The systems also include sensors to monitor volts, amps, watts, frequency, and other pertinent electrical power data of individual generator sets and an overall system.

Grounding System

Pulserplus is an all-digital, high-resistance grounding system designed to allow industrial process plants to operate at 100% of capacity during temporary ground-fault conditions. Data logging is a standard feature of the Pulserplus, making it easier to troubleshoot and correct faulty process conditions during normal daily maintenance schedules with less emergency or overtime expense.

UPS System

The PureWave UPS system provides backup power for 30 sec at 100% load and up to 60 sec at partial loads. The system uses an offline design in which the batteries are electrically connected only during outages. The expandable system is available in ratings from 313kVA to 1250kVA and 380V to 600V. It also comes with a five-year, 625-megajoule-per-battery-string unconditional warranty on the batteries.

UPS Series

The SmartPro 2U series of uninterruptible power supply (UPS) systems features battery backup, automatic voltage regulation, surge suppression, and line-noise filtering. A microprocessor controls all UPS functions and uses an instruction set to monitor incoming power and environmental conditions. All three models (1400VA, 2200VA, and 3000VA) have a slim-line cabinet design that accommodates two units. Other features include an external battery connector, dual-output circuit breakers, and an emergency power-off connection.

AC Line Reactors

This line of AC line reactors protects sensitive equipment by reducing line problems. The reactors are available from 2A to 600A and 1 hp to 500 hp. Voltage ratings include 208V, 240V, 480V, and 600V at 3% impedance. The 480V and 600V models also are available at 5% impedance. A DIN-rail adapter plate is an option for sizes up to and including 16A. All reactors come with a limited 10-year warranty.
