240W Programmable Desktop Type Battery Charger UL60950-1 ENC-240 series IEC60950-1 ■ Features Charger for lead-acid batteries (flooded, Gel and AGM) and li-ion batteries (lithium iron and lithium manganese) Built-in 3 stage programmable charging curve Universal AC input / Full range Built-in active PFC function Fanless design, cooling by free air convection Built-in temperature compensation function Protection: Short circuit / Over voltage /Over temperature / ■ Applications Radio system backup solution Electric scooter charger Surveillance system Battery under voltage / Battery over voltage / Battery reverse polarity protection 3 years warranty ■ 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℃ under free air convection. ■ Model Encoding ENC - 240 - 24 Nominal voltage Rated wattage Series name File Name:ENC-240-SPEC 2017-02-13 240W Programmable Desktop Type Battery Charger ENC-240 series SPECIFICATION MODEL OUTPUT ENC-240-24 ENC-240-48 BOOST CHARGE VOLTAGE(Vboost)(default) 14.4V ENC-240-12 28.8V 57.6V 55.2V FLOAT CHARGE VOLTAGE(Vfloat)(default) 13.8V 27.6V CHARGE VOLTAGE RANGE Note.3 9 ~ 15V 18 ~ 30V 36 ~ 60V OUTPUT CURRENT(CC) (default) 16A 8A 4A RATED POWER 230.4W 230.4W 30 ~ 85AH 15 ~ 45AH 230.4W RECOMMENDED BATTERY CAPACITY (AMP HOURS) Note.4 60 ~ 170AH LEAKAGE CURRENT FROM <1mA BATTERY (Typ.)

Please contact battery vendor and MEAN WELL for details. 2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 3. This is the range when programming Vboost or Vfloat by using SBP-001, the smart battery charging programmer. 4. This is MEAN WELL's suggested range. Please consult your battery manufacturer for their suggestions about maximum charging current limitation. 5. Derating may be needed under low input voltages. Please check the derating curve for more details. 6. This protection mechanism is specified for the case the short circuit occurs after the charger is turned on. 7. Each model incorporates a MCU-controlled dynamic over voltage protection, which is about 115% of Vboost over Constant Current stage and Constant Voltage stage whereas 115% of Vfloat over Float stage. 8. The battery charger is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
