| GSAC-8.507BC BATTERY CHARGER Type GSAC-8.507BC Vin 230 VRMS Vout 8.5 V Iout 700 mA FEATURES Charge of NiCd or NiMH batteries Switch mode constant current generation Three level charging current (fast, trickle, zero charging current) Overcharge detection by - V and T/t under internal microprocessor control No discharge of the battery when charger is turned off Initial trickle charge for deeply discharged batteries Maximum battery voltage protection Maximum battery temperature protection Timer back up protection Output short circuit protection Detection of fault battery Charge status displayed by LED European or UK plug DESCRIPTION The GSAC-8.507BC is a high efficiency battery charger for connection to the mains and to be used with 5 cells NiCd and NiMH batteries. Two versions of the INPUT PLUG ADAPTOR are available: EUROPEAN VERSION : GSAC-8.507BC-1 (ORDERING NUMBER) UK VERSION : GSAC-8.507BC-2 (ORDERING NUMBER) (See pag. 3 for mechanical data) February 1994 1/4 GSAC-8.507BC ELECTRICAL CHARACTERISTICS (Tamb = 25C unless otherwise specified) Symbol Vin Ichf Icht Parameter AC Input Voltage Fast Charge Current Trickle Charge Current Test Conditions Ich = 0 to 0.7A Vin = 187 to 264 Vrms Vbattery = 5 to 8.2V Vin = 187 to 264 Vrms Vbattery = 1 to 5V or 0C < Tbatt < 10C or charge completed Vin = 187 to 264 Vrms Vin = 187 to 264 Vrms Ich = 0.7A Vin = 187 to 264 Vrms Ich = 0.0A Vin = 187 to 264 Vrms Ich = 0.7A Vin = 187 to 264 Vrms Ich = 0.03 to 0.7A -20 -25 8.2 Min 187 0.65 20 Typ 230 0.70 30 Max 264 0.75 40 Unit Vrms A mA C Vbatt Tco tout fs Top Tstg Returned Charge Maximum Battery Voltage Protection Battery Temperature Cut Off Time Out Protection Duration Switching Frequency Operating Ambient Temperature Range Storage Temperature Range 95 8.5 50 2 100 +60 +85 8.7 % V C hours kHz C C Status Red ON Green ON - Fast charge (Ich = 0,7A) - Charge Completed (Ich = 0.03A) - Timer elapsed Anomalous battery conditions (Ich = 0.0A) - Initial Tbattery < 0 C - Initial Tbattery > 40 C - Tbattery > 50 C - Faulty battery Condition Red Flashing Green Flashing OFF (Ich = 0.03A) - Initial charge of deeply discharged batteries - 0 C < Tbatt < 10 C Battery not connected NOTES 1 - The battery temperature detection is a function of the characteristics of the NTC resistor used inside the battery pack. Please consult factory. 2 - Different fast charge and trickle charge currents, and different time out are available on request (Maximum charge current cannot exceed 1A). 3 - For connector to the battery pack please consult factory. 2/4 GSAC-8.507BC CONNECTION DIAGRAM AND MECHANICAL DATA European Plug Version 36 (1.42) 92 (3.62) 2 (0.07) 3 (0.12) 77 (3.03) 20 (0.79) 5 (0.20) 18 (0.71) 15 (0.59) Bicolor LED 52.5 (2.07) 6 (0.24) 1 (0.04) 90 (3.54) 8.5 (0.33) 8 (0.31) 18.5 (0.73) 4 (0.16) 7 (0.28) 3 Wires: 8.8 (0.35) 4 (0.16) 18.5 (0.73) 34 (1.34) + Vout RED - Vout BLACK NTC Green Total cable length = 2000 (78.8) 13.5 (0.53) UK Plug Version 36 (1.42) 92 (3.62) 2 (0.07) 3 (0.12) 77 (3.03) 20 (0.79) 5 (0.20) 15 (0.59) Bicolor LED 18 (0.71) 52.5 (2.07) 6 (0.24) 1 (0.04) 8.5 (0.33) 11.5 (0.45) 22.2 (0.87) 87 (3.43) 8 (0.31) 18 (0.71) 22.5 (0.86) 4 (0.16) 6.35 (0.25) 4 (0.16) 50 (1.97) 9.8 (0.39) 22.2 (0.87) 14 (0.55) European View 8 (0.31) Output connector to be defined according to customer specifications Dimensions in mm (inches). 3/4 GSAC-8.507BC Information furnished is believed to be accurate and reliable.
