1800W 40A DC to DC Adjustable Constant Voltage and Current Power Supply Module
This is a non-isolated DC power converter module. With high power and stable output, it converts 10-60VDC to 12-97V DC. High-quality components ensure high conversion efficiency, up to 97%. Designed with a smart temperature control fan, which will automatically work when the temperature reaches about 60℃, and stop when the temperature drops below 60℃. Widely used for high power solar street lamp driving, various LED lighting CV driving, vehicle-mounted and mobile device power supply, DIY adjustable CV CC power supply, solar power charging, and various battery charging.
- The MLCC ceramic capacitor is added to the input and output, and the output ripple is significantly reduced, which is about 100mV at 48V to 72V 4A
- With airfoil-type heat dissipation, the heat dissipation effect is very good, and the output power is even greater (the power of the 48V input and fan can reach around 1800W). The 100V 210A TO-247 large package power tube has a large power margin and good dynamic response
- Temperature-controlled fans, with hydraulic bearing fans, have a very good balance between noise and heat dissipation. When the load is light, the fan does not rotate. After the temperature of the load reaches approximately 60 degrees, the fan automatically turns. Reduce noise and extend life
- Undervoltage protection is adjustable, which can effectively protect a variety of batteries and can also be used for solar cells
- Input voltage: 8 to 60V
- Input Current: 10V-30V input voltage, maximum current is 35A-40A; 31-60V input voltage, maximum current is 30A-35A
- Quiescent current: 15mA (measured at 12V to 20V, the higher output voltage will increase the quiescent current)
- Output voltage: 12 – 97V continuously adjustable
- Output Current: 35A MAX,
- Over 15A replace existing heatsink with bigger heatsink and fan to enhance heat dissipation
- Related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be
- Constant Range: (potentiometer) 0.8-28A(+/-0.3A)
- Output Power: Input voltage * load current (less 5% loss due to efficiency)
- Working temperature: -40 to + 85 degrees (ambient temperature is too high, please enhance heat dissipation)
- Operating frequency: 150KHz
- Conversion efficiency: up to 93 to 897%
- Overcurrent protection: Yes (with reduced flow adjustment, adjustable output current limit, currently exceeds the current limit, the output current is automatically reduced to a minimum 5A, vary according to the nature of the load current.)
- Short circuit protection: Yes, 3 20A fuses are connected in parallel, which can protect the risk of accidental short circuit of output.
- Input reverse polarity protection Reverse Input Protection: Yes (150A power MOS reverse protection)
- Input Low Voltage Protection: Yes (10V-50V adjustable, self-recovery)
- Input Over Current Protection: Yes (automatically protect when input is more than 40A, and power supply voltage will not increase)
- Reverse Input Protection: Yes (150A power MOS tube, can be connected reversely for a long time)
- Output Counter filling: Yes, for charging blocking diode is not required.
- Installation Hole: Four 3mm screws
- Connection Type: Solderless terminals output
- Module dimensions (L x W x H) : 130x52x80
- Weight 419 g
1 x 1800W 40A DC to DC Adjustable Constant Voltage and Current Power Supply Module
4 x Copper alloy standoff with Nuts (50mm)
