Description
| AUTOMATIC INPUT OF RESERVE ABP 3/3 | Automatic input of the reserve ABP - 3/3 is designed to control the voltage using a microprocessor through two independent three - phase inputs and switch the three - phase load in the event of an accident from the main input to the backup using an external actuator. | |||||
| Rated operational voltage 380 V, 50 Hz The upper threshold of the emergency voltage value (phase) "Uv" min / max 230/270 V The lower threshold of the emergency voltage value (phase) "Un" min / max 150/200 V Hysteresis of the lower threshold "ΔUн" min / max 5/30 V Phase imbalance "Uв - Un" min / max 10/100 V Delay of disconnection of the main input relay in the event of an “toff (s)" min / max 0/20 s Delay on switching on the backup input relay “on (s)" min / max 0/10 s Delay on the return switching to the main input during normalization of the mains voltage “return (m)” min / max 0/30 (no refund) min Switched contact current (AC1 250 V) max 7 A Overall dimensions of the block 71х90х60 mm Weight, no more than 0.3 kg Warranty period - 2 years. We recommend using a spark suppression chain with ABP - 3/3. To protect the line from sparks in single - phase and three - phase networks It is recommended that a spark arrester be connected parallel to the starter coil chain R - 33 Ohm 3 W, C - 1 uF 400 V. |
