SYSTEM DESCRIPTION General information RCH-20 is designed to charge the NiMH battery pack for the Tron TR20 GMDSS and Tron TR20 PLUS handheld VHF radios. It is a dual slot intelligent rapid charger with microprocessor control. It will fully charge an empty battery pack in less than 4 hours. It is designed to operate from 12 ñ24 VDC or 115 / 230VAC with an external adapter. It is equipped with mounting holes for wall mounting or mounting on a table or shelf. RCH-20 2-1 2. TECHNICAL SPECIFICATION General Dual slot rapid charger with trickle charging. Wall and table mountable. Operating voltage: 12 - 24VDC (30VDC max) 115/230VAC with external mains adapter. Current consumption: < 600mA @12VDC Charging current: 450 ñ 500mA (Rapid charge) Trickle charge approx 10mA Charge termination method: ∆V, ∆t and timeout. Charging time: < 4 hours on a fully discharged NiMH battery (X-80059) Operating temperature range: 0 to +40∞C. Size: 155mm wide x 69mm height x 83mm depth Weight : Approx. 300g RCH-20 3-1 3. FUNCTIONAL DESCRIPTION Precautions and Warnings Batteries The rechargeable battery is of NiMH type with a capacity of 7.2V/1500mAh. The following should be noticed: • Do not short-circuit, solder, crush, disassemble or incinerate the battery pack. This may result in fire, explosion and severe burn hazard. • Avoid charging batteries below 0 °C or above 40 °C. Connectors and cables When handling connectors and cables, notice the following warnings: • Do not force plugs in place, as this may damage the pins in the plugs. Storage and safe handling Storage temperature range is from ñ30∞C to +70∞C and operating temperature is from 0 °C to +40 °C. Cleaning of the equipment can be done with a cloth soaked in a mixture of ordinary dish- detergent and water. RCH-20 4-1 4. OPERATING INSTRUCTIONS Operation The charger RCH-20 is a dual slot quick charger. The charger will accept a complete radio or the battery alone (see fig 4). If two batteries are present, the charger will automatically start fast charging the second battery when the first battery is fully charged. The first battery will then be trickle charged to keep it fully charged. Fig. 1 The charger operates from 12 ñ 24 VDC or from 115 / 230 VAC using an appropriate adapter. When using DC supply, the DC cable (80084) should be used. The connector is a standard 5.5mm AC adaptor type. To prevent problems with wrong polarity the RCH-20 is designed to be independent of the power supply polarity. The charger has two LED indicators, one for each battery. They have the follo…
