Votronic Pb 1280 SMT 2B Automatic charger

Fully automatic battery charger with 2 charging outputs for emergency and special vehicles, high-quality motorhomes and the marine sector. Votronic chargers in the "Pb SMT" series are characterised by their compact design, low weight (high-frequency switching power supply, switch mode technology) and full charging power even with large deviations in the mains supply (undervoltage/overvoltage, sine wave, frequency).

An intelligent microprocessor in conjunction with robust power electronics ensures monitoring-free, battery-friendly charging, even in continuous operation. Modern IUoU charging characteristics for lead-acid, gel and AGM batteries as well as modern lithium-LiFePO4 batteries ensure that the on-board battery is optimally charged worldwide (110 V/230 V). Connected consumers are automatically supplied with power.

The integrated battery regeneration keeps the battery fit during long downtimes and ensures a long service life. The battery can remain connected to the charger without monitoring and overcharging is impossible. The integrated on-board filter ensures smooth interaction with other charging sources. Even if the parking space only has a weakly fused mains connection, it is still possible to charge with reduced power using the silent run or AC power limit function.

Battery outputs

1. Main charging output "A", 3 charging programmes can be set depending on the battery type (see Charging programmes)
2. Battery charging output "Start": For support charging and charge retention of the vehicle starter battery with its own charge monitoring

Charging programmes

• "Gel": Charging programme for gel batteries, characteristic curve IU1oU2oU3:
  Adapted to sealed, gas-tight gel/dryfit batteries with fixed electrolyte, which generally require a higher charging voltage level and longer U1 holding times in order to achieve short charging times with particularly high capacity storage and to avoid long-term battery "starvation".
  
  
• "AGM": Charging programme for AGM/fleece batteries, characteristic curve IU1oU2oU3:
  Intended for charging sealed, gas-tight AGM (Absorbent Glass Mat) batteries in lead-fleece technology, which require a particularly high U1 level with coordinated holding times for full charging and then a moderate U2 level for charge retention (plate and round cell technology).
  
  
• "UNIVERSAL": Charging programme for lead-acid/wet/AGM batteries, characteristic curve IU1oU2oU3: Universal programme for charging and charge retention of acid batteries in vehicles (mixed mobile/stationary). With a medium U1 level, still offers short charging times, a good charging factor and good acid mixing for open and closed, low-maintenance, maintenance-free standard, traction, lighting, solar and heavy-duty batteries, as well as AGM batteries with a normal U1 level.
