RS485-Bus radio AC meter, maximum current 65A, standby loss only 0.5 watts. Series installation device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. Accuracy class B (1%). With RS485 interface. Connection to the Eltako RS485 bus. Cross-wiring bus and power supply with jumper. The counter value, the instantaneous power and the serial number are transferred to the bus - e.g. for transmission to an external computer, the software GFVS 4.0 or GFVS-Energy - and also via the FAM14 to the radio network. For this, it is necessary that a device address is assigned by the FAM14 radio antenna module as described in the operating instructions. Display also with FEA65D. The AC meter measures the active energy based on the current flowing between the Ein­gang and the output. The own consumption of only a maximum of 0.5 watts is not measured. Like all counters without MID declaration of conformity in Europe, it is not approved for monetary electricity accounting. An external conductor with a current of up to 65A can be connected. The starting current is 4OmA. In operation, the rotary switch must be set to AUTO. The power reference is indicated by a flashing LED. If L-input and L-output were swapped during connection, an HT/NT-Shift telegram is sent every 20 seconds to indicate the connection error. With an expected load of more than 50%, a ventilation distance of 1/2 division unit to adjacent devices must be observed. For this purpose, 2 spacers DS14 are included in the delivery and apart from the short jumper, two further long jumpers are also included.This text is machine translated.
