HPHA2 - 1

NEW UNITY POWER FACTOR FRONT END PICO HPHA2 2000 Watt AC-DC Converter Single or 3 Phase AC Input Fixed Frequency: 100 Khz PICO's HPHA2 is the perfect front end for your universal AC for your single phase or 3 phase input / DC output applications. The standard 2.5" x 4.6" x 0.5" footprint is one of the smallest on the market today in this power range. Providing a 365V regulated DC output, it can be used as a front end for PICO's FD/MD/LFD/LMD/LPD/PD and HPD series of DC-DC converters which can provide from 3.3V to 300V DC. Also, many laser and motor applications are able to use the HPHA2's 365V DC output directly. For different output voltages and for expanded operating termperature, please consult factory. Full Electrical Specifications: NOTE: Regulated 365V DC Output can be used directly for many Motor, Laser, and Meets EN/IEC 61000-3-2 Requirements Universal Input Voltage (47 to 440Hz) (85 to 250V AC) or 208V AC ±20%. Line-ToLine Three Phase Input Standard Output Power: 2000W (Derate from 220V AC to 170V AC at the rate of 0.5% per volt) Power Factor: 0.99 (from 50% to 100% FL) Synchronizing Pin: For systems needing synchronization, a 100 KHz synchronizing signal is available. Enable Pin: For preventing your Pico DC-DC Converter from turning on until the output of the HPHA2 is within acceptable limits. Connected directly to the Shut Down Pin of PICO's LP/P/HP DC-DC modules, the enable pin will keep the DC-DC module off until the HPHA2's output is within acceptable limits. If the DC-DC module is supplying heavy loads, this means this won't allow the DC-DC Converter to turn on at <300 volts input, where the HPHA2 would have to supply current of I=Power/Vout. Efficiency: 90% or better (95% minimum from 170 to 250V AC or for three phase input) Cost: Only $442.55 (Quantity: 1 to 99 pieces). Universal Input Voltage (47 to 440 Hz): From 85 to 250V AC. NOTE: For 110/220V AC operation, make no connection to "AC3" Derated output power below 220V AC (see "Output Power " below) Power Factor will be diminished for frequencies greater than 60 Hz. For spe For Best Efficiency, operation from 170 to 250V AC recommended. (Typica 220V AC input) Three Phase Input: 208V AC ±20% line-to-line three phase input Output Power: 2000 Watts maximum @ 220V AC. Derate output power linea power @ 170 VAC Input = 1,500 W). 1,000 Watts maximum @ 110 VAC. Der to 85 VAC (Maximum power @85 VAC Input = 700 Watts). Output Voltage Tolerance at Full Load: ±2% Operating Frequency: 100KHz Operating Temperature: 0ºC to +85ºC baseplate with no power rating requir Required Output Capacitor: 1.5m F to 1200µF recommended at 2000W. Th See formula for other power levels, line frequency or Vpp ripple. NOTE: Output Capacitor must be connected or the Power Supply Isolation: Input to Output: None Input/Output to Baseplate: 2121V DC Load Regulation: (10% to 100% Load ±3%) Thermal Shutdown: 90 to 100ºC Baseplate Short Circuit Protection: The HPHA2 requires a 15 Amp Fast-Blow fuse in s Weight: 7.2 ounces (231 grams) Ty

NOTES: (1) To HPHA2 Chassis or No Connection (2) D1 Not needed for single DC-DC Module, for Multiple DC-DC Modules. (3) Damage to unit will occur without C1 = 450 VDC 800 - 1500 µF (Electrolytic Capacitor External). Capacitor can be paralleled for desired capacitance (1500 µF Max). Connect C1 directly to output terminals using separate traces for load connections. *(4) PICO compatible units include LPD/LMD/FD and MD Series. (Expanded operating temperature LFD/LMD/FD and MD Series). PICO recommends using an output capacitor large enough in value to limit the ripple voltage to 10Vpp. For the...

*In units ºC/W To convert from LMF (linear feet per minute), you need to multiply the LFM number by the cross sectional area of the fan (in square feet). Thermal Derating Examples: Use the equation from application notes, From Table 1, get Trca): Tcase-Tambient=Trca *Pout*(¹/n - 1) 1) What is the maximum output power from HPHA1 module in a 25ºC ambient if the efficiency is 90% and the case temperature is not to exceed 85ºC? a) in free air, no heatsink (From Table 1, use Trca=5.10) Pout = (85ºC-25ºC) / 5.1*(¹/0.9 - 1) =105.8 Watts b) in 200 LFM airflow, with CH heatsink: From Table 1: use...
