Superior performance engineered for high demands in extreme conditions.

Suitable for a wide range of applications, the Mass 24/50-2 charger is engineered to meet the needs of commercial and recreational applications. Compatible with all battery types, this charger is ideal for larger battery banks. The ability to be paralleled with other Mass chargers makes it an excellent choice for larger battery banks.

Programmable 3+ step automatic charging system provides a safe and efficient charge and allows the Mass 24/50-5  to match battery manufacturer charging requirements. To extend battery life, an included temperature sensor relays battery condition so that the charger can tailor output to meet the changing needs. Power factor correction provides a consistent charge even when using less than ideal AC sources.

The durable, lightweight anodized aluminum and stainless steel casing provides excellent protection to internal circuitry. Internal components have been coated to prevent corrosion and better function in damp and condensation prone locations. The 180,000 hours MTBF (mean time between failures) provides the confidence of reliability.
