Square Type Moving Coil Power Meter,Analogue Panel Meter Wattmeter Model:90°SF-144-3 SF-96-3 SF-72-3 SF-48-3 Varmeter Model:90°SF-144-3 SF-96-3 SF-72-3 SF-48-3 > Analog panel meter composed of a core- magnet moving coil movement and a built in or a separate power converter. Power meters are intended for measuring active and reactive power in single phase or three phase networks, with balanced or unbalanced load. Nominal mark: active power is W and reactive power is Var. Accuracy: class 1.5 Specification: Voltage: 50V, 100V, 380V, 240V, 415V, 400V, 380V, 220/380V, 240/415V Current: 1A or 5A The voltage circuits of the meter is connected with voltage transformers. Which secondary voltage is 100V and the current circuits connected with current transformers, which secondary current is 5A. Wattmeters and Varmeters with converter for three-phase three wires or four wire and single phase. Case: on-combustile ABS plastic material is used for makingSF series'external case,and PPO plastic material is used forSF series's base; while Non-combustible PC plastic material is used for makingSFT series'external case and base. Both of which will not suffer deformity under long-term use at 70 and 120 respectively. Mounting:SF series is flush mounting with bracket,SFT series(48,72,96,120) is slippage type. Note: when these meters externally connected with potential transformer in three-phase four-wire system, please specify line voltage or phase voltage. External converter of din rail mounting type.
