PAH450S48-28

PAH300-450 Series https://product.tdk.com/en/power/pah www.emea.lambda.tdk.com/pah 300-450W Half Brick DC-DC Converters The PAH300, PAH350 and PAH450 series of isolated half brick DC-DC converters operate from a 24V or 48V nominal dc input and are rated at 300W to 450W. Output voltages are 12V, 28V or 48V and can be adjusted over a wide range using the trim terminal by up to -40% to +18%. Remote sense and remote on/off are included as standard. The power modules can be conduction cooled to a cold plate or fitted with an optional heatsink. These efficient converters are well suited for distributed power architectures and power systems. Features Benefits • Wide Range Inputs • Operates From Batteries or DC Power Systems • Baseplate Cooled • Can be Conduction or Convection Cooled with a Heatsink • -40 to +100°C Baseplate Temperature • Operates in Harsh Environments • Up to 92% Efficient • Easier To Cool In the End System • Fixed Switching Frequency • Predictable Switching Noise Model Selector Model Input Voltage (V) Output Voltage (V) Adjustment Range (V) Maximum Current (A) Maximum Power (W) Input Current (A) nominal input, 100% load Efficiency (%) nominal input, 100% load Overvoltage Protection (%) PAH300S24-12 PAH300S48-12 PAH350S48-12 PAH300S24-28 PAH350S24-28 PAH300S48-28 PAH350S48-28 PAH450S48-28 PAH350S24-48 PAH450S48-48 18 - 36 36 - 76 36 - 76 18 - 36 18 - 36 36 - 76 36 - 76 36 - 76 18 - 36 36 - 76 12 12 12 28 28 28 28 28 48 48 7.2 - 13.2 7.2 - 13.2 7.2 - 13.2 16.8 - 33.0 16.8 - 33.0 16.8 - 33.0 16.8 - 33.0 16.8 - 33.0 28.8 - 52.8 28.8 - 57.6 25 25 29.2 11 12.5 11 12.5 16 7.3 9.4 300 300 350 308 350 308 350 448 350 451 14.71 7.02 8.25 15.1 17.36 7.21 8.24 10.3 17.36 10.4 87 90 89 88 88 90 89 92 87 92 115 - 135 115 - 135 115 - 135 125 - 140 125 - 140 125 - 140 125 - 140 125 - 145 115 - 140 125 - 145 PAH Series 450 S Output Power (W) 300, 350, 450 Simple Function 24 - 28 Nominal Input 24 = 24V 48 = 48V * Contact factory for availability on other models Output Voltage 12, 28, 48 /T Options Suffix Description Blank M3 tapped mounting inserts /T 3.3mm non-threaded inserts /P Positive logic remote On/Off (Not on PAH450S)* Related Products DC-DC Converters DC-DC Converters DC-DC Converters Heatsink Heatsink Heatsink Part Number PAF600F24-48 PH50A280 to PH600A280 i7A HAH-10L HAH-10T HAH-15L Description 600W, 24 & 48V Input Full Brick DC-DC Converters 50W to 600W, 200 to 425V Input DC-DC Converters 500 to 700W, Non-isolated Step Down DC-DC Converters Half brick 25mm longitudinal fins Half brick 25mm transverse fins Half brick 38.1mm longitudinal fins PAH300-450 Series 1 Specifications Model Input Input Voltage range - Input Current - Efficiency - Conducted & Radiated EMI - Immunity - Safety Certifications and Markings - PAH300-450 See model selector See model selector See model selector EN55011/EN55032-A, FCC Class A, VCCI-A (External components are required, consult Instruction manual on website) IEC61000-4-2, -3, -4, -5, -6 (External component are required, consult Immunity Data on website) IEC/UL/CSA/EN62368-1, 60950-1, CE Mark and UKCA Mark Immunity Test Standard Test Level Criteria ESD EN61000-4-2 Air ±10kV and contact ±5kV A 80M -1GHz: 10V/m Radiated Susceptibility EN61000-4-3 1.4 - 2.0GHz: 3V/m A 2.0 - 2.7GHz: 1V/m Electrical Fast Transient Burst EN61000-4-4 ±2.4kV A Surge EN61000-4-5 Common, Normal ± 600V A Conducted Susceptibility EN61000-4-6 10Vrms A Notes External components are required (Consult Immunity Data on website) Specifications Model PAH300-450 Output Output Voltage Tolerance % ±1 Output Voltage Adjustment - See model selector Switching Frequency kHz PAH300-350S24: 330, PAH300-350S48: 370, PAH450S48-28 400, PAH450S48-48: 460 Line Regulation mV 12V: 24, 28V: 56, 48V: 96 Load Regulation mV 12V: 24, 28V: 56, 48V: 96 External Load Capacitance - Contact Technical Sales Ripple & Noise mV 12V: 200; 28V: 280 (240 for PAH300 ), 48V: 480 Temperature Coefficient %/°C 0.02 Minimum Load - No minimum load required Overcurrent Protection % 105 - 140, constant current with automatic recovery Overvoltage Protection - See model selector, cycle input or remote on/off to reset Overtemperature Protection °C 105 - 130 base-plate Remote Sense - Yes Remote On/Off - Yes; Low = ON, High = OFF Parallel Operation - Not possible Environmental Operating Temperature (Baseplate) °C -40 to +100.
