Voltage stabilizer B2-2 (B2 2, B 2-2)
Voltage stabilizer B2-2 are designed to operate at an ambient temperature of 243 to 323 ° K (-30 to +50 ° C), relative humidity of 98%, a mains voltage of 220 ± 22V.
B2-2 - the maximum load current - 2.2 A.
The devices are on the network, the AC voltage (220 ± 22) frequency (50 ± 0,5) Hz, with harmonic content up to 5%.
Voltage stabilizer B2-2 provides a voltage of 220 V, the permissible load current with 2.2 A. The basic error of the output voltage does not exceed ± 1,5%.
The output voltage is isolated from the housing. Instability of the output voltage when the input voltage from the nominal value by 10% for any permissible load current during the measurement time 5 min is less than ± 1%.
The instability of the output voltage when the load changes from nominal to zero does not exceed ± 2%. Additional error voltage output at the temperature of 10 ° C under any load current does not exceed ± 0,5%.
Output voltage drift over 8 hours of continuous operation and for any zetih 10 minutes and 8 hours, excluding the time samoprogreva, does not exceed the basic error of the output voltage. Harmonic content of output voltage under all possible values of the input voltage, load, and the entire range of operating temperatures do not exceed 10%.
