EST 1K / 2K
voltage regulator
EST 1K
These two units maintain a constant output supply when voltage oscillates between 140 and 250 V AC. They allow 1000 VA (EST 1K) or 2000 VA (EST 2K) load connection.
Both devices feature dierent protections to ensure output signal integrity: protections against overvoltage, overload, or short circuits. They also have a circuit breaker on their rear pa-
nel. To avoid noises coming from ON/OFF switch, They also feature a time delay circuit (3 or 6 sec.), after this time, normal operating mode starts automatically. A large display shows the
information regarding devices status, like input, output and current voltage.
FEATURES
- Control and regulation by microprocessor (MPU).
- Large LCD screen.
- High accuracy regulation.
- Protections against overvoltage, overload or output short circuit.
- 3 seconds time delay.
