Description

ENC-240 is a single output 240W AC/DC desktop-type charger with 3 stage charging curve. In addition to the embedded pre-defined charging curves, the default curve is programmable and thus able to accommodate different types of batteries, such as lead-acid batteries (gel, flooded, and AGM) and li-ion batteries (lithium iron and lithium manganese). With the rugged mechanical design along with the high-efficiency circuitry, ENC-240 operates for the ambient temperature range -30~+70°C under free air convection.

NOTE	Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. This is the range when programming Vboost or Vfloat by using SBP-001, the smart battery charging programmer. This is MEAN WELL’s suggested range. Please consult your battery manufacturer for their suggestions about the maximum charging current limitation. Derating may be needed under low input voltages. Please check the derating curve for more details. This protection mechanism is specified in case the short circuit occurs after the charger is turned on. Each model incorporates an MCU-controlled dynamic over-voltage protection, which is about 115% of boost over the Constant Current stage and Constant Voltage stage whereas 115% of Vfloat over the Float stage. The battery charger is considered an independent unit, but the final equipment still needs to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these MC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com) 9. The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitudes higher than 2000m(6500ft. ⅚ Product Liability Disclaimer: For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx.

Charging Curve

This series provides a 3-stage charging. The default curve is programmable, whereas other pre-defined curves can be activated by means of the DIP switch; please refer to the table below and the Mechanical Specification.
To accommodate the parameters of the charging curve, SBP-001, the smart battery charging programmer designed by MEAN WELL, and a personal computer are needed. Please contact MEAN WELL for details.

Default 3 stage charging curve

Suitable for lead-acid batteries (flooded, Gel and AGM) and Li-ion batteries (lithium iron and lithium manganese).
