1. Introduction

the zero-crossing detector modulation conversion principle is used to produce a corresponding linear DC output signal proportional to true power factor of the power system. the transducers can be use in a single or three phase system.

Applied Standards & Rules:

Measuring and conversion: IEC 688 / 1992 - 04

Dielectrical strength: IEC 688 2KVac / 1 min.

Surge and Impulse test: ANSI C37.90 / 1989,IEC 255-3 (1989) 4KV 1.2 x 50 us

Reference Standard: GB/T 13850-1998(IEC688-1992)

Models and specifications:

GPF- Frequency Transmitter: Accuracy: 0.5%

Input & Output parameters

Note:
1. Uni. = uni-direction = 0 to +span bi = bi-direction = -span to 0 to +span referring to calibration
2. for internal powered type... Zero based outputs and Vn operation range 85%~115%
