Recalibration unit for automated energy consumption meters UAPS-1 is designed for recalibration of static single-and three-phase power consumption meters, measuring active and reactive energy in two directions.
The unit is manufactured in three variants:
- UAPS-1
- UAPS-1M differs from UAPS-1 by higher output power of voltage and current modules
- UAPS-1 / P equipped with a universal panel for swift hooking of the recalibrated meters.
The unit operates automatically under PC control.
Number of simultaneously recalibrated meters of the same type:
- 6 three-phase or 18 single-phase meters at UAPS-1and UAPS-1M
- 6 three-phase or single-phase at the workstations from 1st to 6th, up to 12 single-phase with galvanically coupled series and shunt circuits at workstations from 7th to 18th.
O Accuracy class of recalibrated meters-0. 5 and less precise by active energy; 1. 0 and less precise-by reactive energy.
O Accuracy class of recalibrated meters-2. 0 and less precise by active energy at workstations from 7th to 18th ato Accuracy class of recalibrated meters-0. 5 and less precise by active energy; 1. 0 and less precise-by reactive energy.
O Accuracy class of recalibrated meters-2. 0 and less precise by active energy at workstations from 7th to 18th at UAPS-1 / P unit
O Rated values of linear 57. 7v and 230V, linear 100V and 400V phase voltage are set within 0. 7-1. 2 of rated value.
O Outgoing current range at the current module is 0. 001a to 50. 0a for UAPS-1and UAPS-1 / P; 0. 001a to 100. 0a for UAPS-1M
O Vector maximum power of every voltage and current signal phase is min. 40v*A and 50V*A for UAPS-1and UAPS-1 / P units; min. 80a*V and 150V*A for UAPS-1M.
UAPS-1provides for
O Twice quicker recalibration due to automated meter recalibration and adjustment mode exercised under PC control
O Calculation of meter error, comparing error value to previously set admissible deviations, as well as indication for sorting and rejection.
O Recalibration of meters' sensitivity and shunt running
O Generation of meter recalibration protocol as a recordable file that can be printed out.
O No additional errors as human factor is eliminated from the recalibration process.
O Rated values of linear 57. 7v and 230V, linear 100V and 400V phase voltage are set within 0. 7-1. 2 of rated value.
O Outgoing current range at the current module is 0. 001a to 50. 0a for UAPS-1and UAPS-1 / P; 0. 001a to 100. 0a for UAPS-1M
O Vector maximum power of every voltage and current signal phase is min. 40v*A and 50V*A for UAPS-1and UAPS-1 / P units; min. 80a*V and 150V*A for UAPS-1M.
