The regulators of load Steca PR were created in 2004 as a technology of regulator of load of the fifth generation and going up to 900 WC. This product of higher class improves the range Steca Solarix by a posting LCD conceived for the user who expressed as a percentage indicates the state of precise load as a symbol of measure accumulator. The heart of the regulator is the integrated circuit named ATONIC®II which contains a software of regulation improved based on a self-educated algorithm.
Technical characteristics
- Loading of the accumulator shunt by modulation of impulse in width (PWM)
- Regulation of the state of load (PLOUGHSHARE) of the accumulator
- Integrated Ah meter
- Fast loading
- Charge with equalization
- Process of load for the maintenance of the final tension of load
- Automatic Reconnexion of the consumer
- Manual interruption of loading
- Automatic selection of tension (12 V/24 V)
- Compensation of temperature
- Earthing positive (or) Negative with the one of the terminals
- Adjustable parameters manually by two keys
- Function of monitoring of the light during the night
- Interface for power station of prepaiement
Postings
