Name: communication power (high-frequency switching power supply rectifier module) a communication power module Introduction Huayi special new energy production AC220-DC24V / 48V series of communications power modules using advanced high-frequency pulse width modulation technology, efficiency has been greatly increase. The machine has regulated high precision, fast dynamic response, low output noise, anti-interference ability, wide operating temperature range of features. N + 1 module structure between the modules can be automatic current balancing power, high-frequency switching power supply system can be set up for the telecommunications, electricity and wireless base stations. Header type module using three and a half meter display, display output current and voltage, simple and practical. Module uses a width of 19 "and a high standard for the 2U chassis, easy to install and can be used for the composition of the power system, and modules can be connected in parallel with the battery, without monitoring unit. The power module is suitable for AC and DC 220VAC 220VDC input conditions Using the occasion. This power module is suitable for AC and DC 110VAC 110VDC input conditions of use applications. The power supply module for DC output 24VDC 10A-60A DC output conditions using the occasion. The power supply module for DC output 48VDC 5A-40A DC output condition of usage scenarios. Second, the communication power module works 1.AC220-DC24 / 48V when converting DC to AC 220V or DC 24V 48V, for DC load use, when the mains power failure, the battery pack regulated output; 2.DC220-DC24 / 48V when the step-down DC-to-DC 24V or 220V DC 48V, for DC load use, when the mains power failure, the battery voltage output; 3. With discharge management type, when the user needs to use a single module, and can be used alone to charge the battery, you can use the power module with communication charge management type, the module converts the AC220 DC24 / 48V output, but also to the intelligent battery charging , when the mains power failure, the battery voltage output; three, communication power module technology parameter 1 Input voltage: single-phase three-wire AC: 220V ± 20% 1 Input Current: ≤10A (RMS) AC input 220V, 48V DC output frequency is 2 when: 50Hz ± 10% 3 Power factor: ≥0.99 4 Efficiency: ≥0.87 5 inrush current: ≤150% Imax (rated input state) ◆ Protection: Input over-voltage protection; output over voltage protection; output current limiting protection; short circuit protection; module parallel protection; over-temperature protection; overcurrent protection; 6 input overvoltage shutdown: 265--275V 7 input undervoltage shutdown: 160--170V 8 AC input range: 160- -270V 9 DC output voltage: 48VDC or -48VDC (42∽58V adjustable) or 24V (21∽29V adjustable) 10 Rated current: 10A, 20A, 25A, 30A, 40A 11 output current limit: Ie + 1A 12 Voltage Regulation: Voltage regulation does not exceed + 0.1% 13 load regulation of the DC output of the set value: no more than + 0.5% 14 regulation accuracy DC output setting value: Not more than DC output setting value of + 0.5% 15 phone balance Heavy murmur: ≤0.5mV 16 peak noise: ≤150mV 17 broadband noise voltage: ≤30 mV (3.4KHZ - 150KHz) ≤20 mV (150KHZ - 30MHz) 18 discrete frequency noise voltage: ≤5 mV (3.4KHZ-- 150KHz) ≤3 mV (150KHZ - 200KHz) ≤2 mV (200KHZ - 500KHz) ≤1 mV (500KHZ - 30MHz) 19 Current level: ≤ + 5% 20 Display Accuracy: ≤ + 5% 21 soft start time : 3--8 seconds 22 Temperature coefficient: DC output does not exceed the set value of + 0.2% 23 Insulation resistance: ≥10MΩ (at room temperature environment) 24 Dielectric Strength: input to ground, input to output is applied to the AC 1500V / 50Hz, the output of applied AC 500V / 50Hz, 1min no flashover, no breakdown 25 EMC: Complies with MII YD / T983-1998 standard model were: HET-4805 HET-4810 HET-4815 HET-4820 HET-4825 HET -4830 HET-4850 HET-2405 HET-2410 HET-2420 HET-2430 HET-2440 HET-2450 (for example: HET-4810 48 refers to a DC voltage of 48V 10 refers to the output current of 10A)
