- Product description
- Charging programmes no. 1, 2, 3 and 5 (gel, AGM, acid, start) adjustable to battery type
- Outstanding charging technology
- The charging voltages are free of peaks and regulated to prevent overcharging
- 1 main charging output and 1 additional auxiliary charging output "S" for support and trickle charging of a starter battery (max. 2 A)
- Starter battery is also charged with full charging current if required (short vehicle service life)
- Fully automatic continuous operation for constant operational readiness of the batteries
- Precise battery temperature compensation, temperature sensor included in the scope of delivery
- Equalisation function (IUIU charging characteristic can be activated manually for cell equalisation charging)
- Intelligent microprocessor control takes into account the simultaneous co-supply of consumers on the battery
- Automatic battery regeneration during long downtimes (twice a week)
- Equalisation of voltage losses on the charging cables for exact compliance with the charging voltages
- Disconnection of the batteries in the event of mains failure, overheating, incorrect behaviour (safety switch per charging output)
- Silent run function can be set (night setback)
- Mains adapter function enables consumers to continue operation and data retention, e.g. when changing batteries
- Electronics protected against moisture
- Variable installation position
- Battery capacity adjustable in 4 stages (16 charging programmes in total)
- Input for sensor (sense) cables, can be used with extra-long charging cables
- Separate signalling output +86 for engine start inhibit with vehicle mains connection
- Voltage equalisation for external diode charging current distributor selectable (+ 0.63V)
- Mains/charging power can be reduced in the event of low-power or restricted mains supply, e.g. weakly fused shore power supply, generator operation, etc. (power limit function)
Optional accessories:
- Remote control S (Art. 2075)
- Remote operating display IP67 (Art. 2081)
- Charger State Monitor IP67 (Art. 2082)
