Product Specification sheet 18J SMPSU T1255-21J INPUT MINIMUM RATED MAXIMUM Input Voltage 90V AC 100 240V AC 264V AC Input Frequency 47 Hz 50 / 60 Hz 63 Hz Input Current * 350mA Inrush Current ** <60A * At 240v ac, maximum Load ** At full-load, 25C, cold start. There shall not be any damage and the input fuse shall not blow OUTPUT Output Voltage 12.0V DC Nominal (Min. 11.4V DC Max. 12.6V DC) Maximum Load Current 1.5A (Max) Maximum Output Power 12W Ripple and Noise * 120mV Output overshoot/undershoot ** 10% (Max) Turn-on Delay 5 Seconds (Max) Hold-up Time *** 10mS (Min) Dynamic Response The power supply shall maintain output transient response time within 10ms with a loading current change from 20% to 80% of maximum current and 0.5A/s rise up or drop down tested at output terminals. * Voltage measured p-p with a 20MHz bandwidth oscilloscope. The output is paralleled with a 10uF low ESR electrolytic capacitor & a 0.1uF ceramic capacitor to ground at rated input and full load condition. ** When power is switched on and off at full load condition. *** At 230V AC 50Hz and maximum load. PROTECTION Over-current Protection * >1.8A and 3.75A (Trip range at 240V AC 50Hz) Short-circuit Protection The adaptors input power shall decrease when the output is short circuited and it shall be able to withstand this condition continuously without damage. There shall be self-recovery to the normal state when the fault condition is removed. * The output voltage will drop when an over-current condition is applied to the output and there shall be self-recovery to the normal state when the over-current condition is removed (auto recovery). www.accesscomms.com.au/specs/adaptor 18J T1210-21J.pdf Page1of5 Copyright 2015 Access Communications Pty Ltd Product Specification sheet 18J SMPSU T1255-21J ENVIRONMENTAL OPERATING STORAGE Temperature 0C to +40C -30C to +70C Relative Humidity 10 ~ 90 % RH. Non-condensing Altitude Sea Level to 2,000 m Vibration and Shock 1.0mm, 10-55Hz, The power supply shall be 15 minutes per designed to withstand normal cycle for each axis transportation vibration per MIL- (X, Y, Z) STD 810D, method 514 and procedures X, as it is mounted in the chassis assembly and packed for shipping. Cooling Natural convection RELIABILITY Mean Time Between Failure When the power supply is operating within the limits of this (MTBF) specification the MTBF shall be at least 20,000 at 25C (MIL HDBK-217F). Burn-in Test The power supply shall withstand a minimum of 4 hours burn-in testing under full load at 35C ~ 40C +/- 5C room temperature. After the test, the product shall operate normally. MECHANICAL Dimensions Refer to the Outline Drawing (Page 4) Weight 125g 10g Input Plug Type Wall type, AU-pin, 2-conductors, <Active, Neutral> Output Cord UL2464, 22AWG * 2C, Black Output Plug 11.0(L) x 5.5(D) x 2.1(ID)mm. Drop Test A sample is to be subjected to three impact tests by dropping from a height of 1000mm 10mm onto a horizontal surface in positions most likely to produce the most adverse results. The horizontal surface consists of hardwood at least 13mm thick, mounted on two layers of plywood each 19mm to 20mm thick, all supported on a concrete or equivalent non-resilient floor. The sample shall subsequently pass an electrical functional test and the case shall not be cracked. SAFETY Compliance Standard AS/NZS60950 Insulation Resistance >10M at 500V DC. Dielectric withstanding 3000V AC 5mA for 1 minute (sample) or for 3 seconds (production). voltage test (Hi-pot test) Primary to Secondary Leakage Current <0.25mA for Class II at maximum input voltage. www.accesscomms.com.au/specs/adaptor 18J T1210-21J.pdf Page2of5 Copyright 2015 Access Communications Pty Ltd
