AC source '' B2-4 ''.

Power supplies. Rectifiers, stabilizers, autotransformers, transient transformers, etc.Blocks and power supplies laboratoryThe B2-4 alternating current source has been produced presumably since 1986. "B2-4" is a mains voltage stabilizer and is intended for power supply of electrical measuring devices with stabilized alternating voltage of industrial frequency. Provides protection of the device and the consumer from overloads and short circuits, has an indication of emergency mode (overcurrent and voltage). Main characteristics: Output voltage: 220 V. Output power 1000 V * A. Instability when the mains voltage changes ± 0.5%, when the load current changes ± 1.5%. Operating temperature range from -Z0 C to +50 C. Power supply: 220 ± 22V, 50 ± 0.5Hz; 220 ± 11V, 400 ± 10Hz. Replaces the previous stabilizers "B2-2" and "B2-3". Dimensions 160x228x308 mm. Weight 13 kg.
