The DEIF CSQ-3 is a microprocessor-controlled multi-function synchroscope meter designed for precise manual or semi-automatic synchronizing of electrical generators with the busbar in industrial and marine power systems. Typically used in power plants, grid synchronization, and electrical distribution systems, the CSQ-3 ensures safe and efficient connection of generators by measuring and comparing voltages, frequencies, and phase angles between the generator and the busbar. Its role is critical in avoiding damaging power surges and ensuring smooth synchronization during generator parallel operation.
Equipped with advanced LED indicators simulating an analog pointer for clear phase difference visualization, the DEIF CSQ-3 offers high user safety with front-panel pushbutton settings hidden under a protective foil, allowing live adjustments without exposure to hazardous voltages. It supports operating voltage ranges suitable for land or marine applications, with robust immunity against harmonic distortions and environmental factors. The device’s dead-bus functionality enhances safety by preventing synchronization attempts when busbar voltage is absent.

Technically, the DEIF CSQ-3 provides accuracy within ±2 electrical degrees and a resolution of 10 degrees through 36 LEDs arranged in a circle. It includes a single SPST-NO relay rated for 8 A at 250 V AC or 8 A at 24 V DC, suitable for controlling synchronization equipment. Operating temperature ranges from -25 °C to +70 °C with high galvanic isolation of 3.75 kV between inputs, outputs, and ground, complying with EN 61010-1 standards. The compact unit measures 96 x 96 x 76 mm and weighs about 0.4 kg, designed for easy panel mounting.
