Specification :

Moving-iron meters EA16, EA17, EA19 and EA12 types are destined to measure a.c. voltage or a.c. current. They measure the true RMS value of a.c. voltage or a.c. current.

* direct measuring ranges:
o I = 100mA...100A,
o U = 6V...1kV,
* measuring ranges with external transformer:
o I = 1A...10 kA,
o U = 4 kV...250 kV,
* accuracy class: 1.5,
* exchangeable scales,
* for requirement
* meters can be made with additional setting pointer and/or the scale underlighting.

Moving-coil meters MA16, MA17, MA19 and MA12 types are destined to measure d.c. voltage or d.c. current and other physical quantities converted into a current or voltage standard signal.

Meters with built-in rectifiers can be used to measure a.c. voltage or a.c. current.

* direct measuring ranges:
o I = 40µA...25A,
o U = 60mV...1000V,
* measuring ranges with external shunts: I = 1A...15kA, (see our offer)
* accuracy class: 1.5,
* exchangeable scales,
* for requirement meters can be made with additional setting pointer and/or the scale underlighting.

Power factor meters FA32 and FA39 type are destined to measure the phase angle difference between the voltage and the current in 1-phase or 3-phase a.c. power networks. In three-phase network assymetrical loaded is demanded to use three meters se

* input voltage for system in 1 phase network: U = 100...500V,
* input voltage for system in 3 phase network symetrical load: U = 100...500V,

* accuracy class: 0.2 for measuring ranges:
48...52 Hz, 58...62 Hz, 140...160 Hz, 180...220 Hz, 380...420 Hz,
* accuracy class: 0.5 for measuring ranges:
45...55 Hz, 45...65 Hz, 55...65 Hz, 360...440 Hz,
* fixing in the panel.

Power meters PA39 type are destined for measurements of the active and reactive power in 1 and 3 phase power network.

* for measuring the active power in single-phase networks,
* for measuring the active power in three-phase three-wire and four-wire power networks, with balanced or unbalanced loads,
* for measuring the reactive power in three-phase three-wire and four-wire power networks,with balanced or unbalanced loads,
* with zero on the left side of the scale, for measuring the unidirectional power flow,
* with zero in the middle of the scale for measuring the bidirectional power flow.
* input voltage: U = to 690V, also for co-operation with voltage transformer,
* current input: I = 1A or 5A, also for co-operation with current transformer,
* accuracy class: 1.5,
