Data sheet DC/DC converter for the SilverLine Input: DC 18...36 V Output: 5.1 V / 8 A MOSFET inverse battery protection Active in-rush current limiting Inpt voltage 18...36 VDC, short term 16...40 V DC (min. 18 V for start) Output voltage 5.1 V DC ± 1%, adjustable 4.5 ... 5.5 V (at front panel) Inverse battery protection via low-loss MOSFET, no fuse replacement necessary Ambient temperature range Tamb Operation: 0°C...+70°C (>60°C: Derating) Storage: -25°C...+85°C Input current < 2.9 A (at Vin=18 V, nominal load) < 1.5 A (at Vin=36 V, nominal load) Continuous loading • with open output typ. 19 mA (preserves battery sources) In-rush current Voltage regulation better than 1% Vout overall Inrush current limiting done with a fixed 4.7R resistor (not a thermistor) which is bridged after the unit is running, so losses are minimised. That means no reset time even at a warm-start. Ripple / Noise < 50 mVPP, incl . spikes (20 MHz bandwidth, 50 Ω measurem.) Overvolt. protection Hold-up time Parallel operation Power back immunity Front panel indicator Efficiency, Reliability etc.* Efficiency Electrolytics (lifecycle) The unit exclusively uses longlife electrolytics, specified for +105°C (cf. ’The SilverLine’, p.2). Electromagnetic Compatibility (EMC) Emissions Class B (EN 55011, EN 55022) radiated noise Class A (EN 55011, EN 55022) line-bound noise Immunity • Static Discharge (ESD) EN 61000-6-2 (includes EN 61000-6-1) EN 61000-4-2, Level 4 (withstands 8 kV direct discharge, 15 kV air discharge) Start / Overload Behaviour • Electromagnetic radiated fields Startup delay Overload Behaviour Almost straight charact., see diagram overleaf • Burst, coupled to: – DCin lines – DCout lines • Surge transients – Differential (±Vin → PE) – Common mode (+Vin → –Vin) • Conducted noise immunity Construction / Mechanics* Housing dimensions and Weight 49 mm x 124 mm x 102 mm (+ DIN rail) • WxHxD above/below 25 mm recommended • Free space for right 10 mm recommended (front view) ventilation 470 g • Weight Design advantages: • All connection blocks are easy to reach as mounted at the front panel. * *For further information see data sheets „The SilverLine“ and „SilverLine Family Branches“ • Input and output are strictly apart from each other and so cannot be mixed up (Input below, output above).
