SP1470 Celab Telephony 750 Watts Uninterruptible Power Supply Specification ■ ■ ■ ■ ■ ■ ■ Integrated battery management system. Designed for street cabinet applications. Non latching thermal protection. 10A output with separate 4A charging facility. Output voltage adjustable from 54V to 58V DC. Automatic and remote controlled battery condition testing. Comprehensive range of management alarms. Input Voltage 230VAC, +15% - 10% Single Phase Input Frequency 47 to 63Hz Emissions/Immunity Standards EMC meets requirement of EN50081-1 & EN50082-1 Inrush Current 15A Typical Output Voltage 54V to 58V (adjustable by potentiometer) Output Current Range 0-10A at 56V Output Regulation Load +/- 1%, Line +/- 0.2% In battery mode the output will be equal to the battery voltage, less 0.5V Output Noise & Ripple 100mV peak to peak, up to 20 MHz Battery Charging Current 4A DC Efficiency >85% at full load Operating Temperature -20°C to +65°C Temperature Coefficient 0.02% per °C Protective Features If ambient temperature exceeds 65°C the power supply is protected by a non-latching thermal cut-out. Insulation - Input to Chassis 1500Vrms Insulation - Output to Chassis Insulation - Input to Output 3750Vrms Insulation - Output to Output Safety Standards Meets BSEN60950, LVD Compliant, CE marked. Current Limit Trip and restart, 20A +/- 1A Overvoltage Protection Low Battery Disconnect Auto Battery Test Feature 100Vrms 100Vrms Trip and restart, 64V +/- 1V 42.5V +/- 0.5V The power supply will automatically load check the battery condition approximately every 20 days (or longer if required) for approximately 20 minutes to establish that the battery is ‘good’. If the battery voltage is below 47 volts, alarm 4 will operate. Alarms The following 6 alarms are isolated and have a pair of contacts that can be factory configured open or closed in normal operation. Alarm 1: Input Mains Good Alarm 2: Output Voltage Good Alarm 3: Power Supply Good Alarm 4: Battery Good Alarm 5: Alarms 1 to 4 in Series Alarm 6: Thermal Cut Out Alarm Indicators Alarms 1 to 4 - Four Green LED’s Output Current Indicator LED display of total output current (including battery charging current) in 2A increments to 16A. Mechanical Specification Mains Input Size Weight Specification Note: IEC 320 connector with 10A fusing 19” rack x 2U high x 240mm deep 6kg For any requirements not specified above, please contact the sales department. ■ The SP1470 series has been specifically designed to reliably withstand the very high and low temperatures experienced in street cabinets. ■ The battery management system enhances the life of the batteries by controlling the charging current and avoiding deep discharge. ■ Regular battery test loading monitors battery health without risk of system failure.
