RuncoN

Automatic Power Factor Controllers

RuncoN Automatic Power Factor Controllers (APFC Relays) are advance microprocessor-based devices designed for power factor correction in low voltage applications. They measure the actual power factor and automatically connect or disconnect capacitors to achieve and maintain the target power factor — with zero requirement of on-site programming.

Available in 9 models across 4 series — PFC, ATSO, 3CT, and EP-844 — our controllers cover 6 to 16 stage configurations for balanced, unbalanced, single-phase, and three-phase systems. All models feature Plug & Play installation, FND/LCD digital display, auto and manual modes, and accuracy of ±0.01 for power factor.

♦ RuncoN APFC RELAY is a full automatic relay — starts working as soon as the power is turned on after connection.
♦ No on-site programming required. Auto sensing works by automatically reading all network values.
♦ Works from as low as 1 AMP even with high CT value at low load.
♦ RELAY works 100% even when phase changes from GRID — no need to change CT wire.
♦ ACCURACY of power factor remains ±0.01 (ability to maintain power factor up to 0.999).
♦ Auto and Manual mode available on all models.
♦ Settable parameters: Number of relays, step time, discharge time.
♦ Available in 6, 8, 12, and 16 stage configurations.
♦ EP-844 specially designed for unbalanced loads — maintains R, Y, B phase separately.
