Aideepen 1200W 20A DC Converter Boost Car Step-up Power Supply Module 8-60V to 12-83V
Specifications
- Module type: 1200W Boost Constant Current Module (Non-isolated)
- Input voltage range: DC10-60V (direct input 10-60V without jumper cap selection voltage)
- Input current: 20A (MAX). Exceeding 15A requires fan cooling (with a 12-24V fan, input current can reach 25A).
- Static working current: 15mA (at 12V input, 20V output; current increases with output voltage).
- Output voltage: 12-83V continuously adjustable (default shipment is 19V; adjust as needed). 12-83V fixed output available for bulk orders.
- Output current: 18A MAX. For currents over 10A, enhance heat dissipation (dependent on input/output voltage difference; larger difference means smaller output current).
- Constant current range: 0.5-18A (+/-0.3A)
- Low battery protection: Adjustable (9-50V)
- Working temperature: -40~+85 degrees Celsius (enhance heat dissipation in high ambient temperatures).
- Working frequency: 150KHz
- Conversion efficiency: 92%-97% (efficiency is related to input/output voltage, current, and pressure).
- Module size (approximate): 140mm*60mm*50mm
Smart Protection
- Input overcurrent protection: Yes (automatic protection at input over 25A; power will not boost).
- Short circuit protection: Yes (includes a 30A input fuse for double protection).
- Input reverse connection protection: Yes (uses a 150A power MOS tube for anti-reverse protection, allowing for prolonged reverse connection).
- Wiring method: 4 x 3mm copper columns, terminal block (use high-current pure copper wire).
- Output power calculation: Output Power = Input Voltage * 20A. For example, at 12V input, Output Power = 12V * 20A = 240W. The maximum power at 12V input is 240W. For 24V input, Output Power = 24V * 20A = 480W.
Guide
Entering low battery protection
This feature prevents excessive battery discharge, which can damage power modules and batteries. To set low battery protection for a 12V battery (e.g., at 10V input): connect the module, adjust RV1 with a screwdriver (clockwise increases voltage, counterclockwise decreases voltage) until the UVLO lamp lights up. When the battery voltage drops to 10V, low battery protection engages, and the power module will not boost (input voltage equals output voltage).
Module Instruction
Components:
- Input filter capacitor: 4 x 470 μF/63V
- Output filter capacitor: 3 x 470 μF/100V
- Adjustments: CV (output voltage), CC (output current), Input low battery protection adjustment.
- Interfaces: VIN-, VIN+, Power Out-, Power Out+
- Fan Interface: 12V Fan Interface
- Cooling: 50MM Fan Mounting Hole*4
Notes
- Do not use short-circuit output mode, as the boost module's circuit structure cannot be adjusted in a short circuit.
- The input power supply voltage must be over 10V.
- When using a switching power supply as the input, connect it first without load and adjust the voltage. Then connect the load. Ensure the switching power supply remains operational throughout. Alternatively, adjust the voltage first, then disconnect the power supply before connecting the load. When powering on the switching power supply and the module, turn on the switching power supply first. This accounts for the switching power supply's ramp-up time. If the voltage is below 10V during ramp-up, the chip may not work, potentially damaging the MOS tube.
- When using constant current mode, the fixed voltage must be higher than the input voltage. For example, if the input voltage is 12V and the no-load output voltage is 15V for a 3.2V LED, this is not allowed. Use at least 4 series LED lights.
Troubleshooting
| Question | Solution |
|---|---|
| Enter short circuit | Check for a short circuit in the switch tube; replace if necessary. |
| The current cannot be adjusted. | Verify the load is correct. Connect to a constant current load, such as LED lights or batteries. |
| The voltage and current cannot be adjusted. | Check for low-battery protection. The power will work when the UVLO lamp is extinguished. |
| Unstable output | Check if the current is adjusted to the minimum or low-voltage protection settings. |
| It is not a stable output voltage, and the input voltage changes greatly. Not available. | This is a boost power supply; it can only increase and regulate voltage. The output voltage must be higher than the input voltage. |
| The project runs well for the first time when the load is connected to the output. But the second melting input fuse. | Possible issues: 1. Output short circuit; 2. Load is too large. Consider changing the fuse. |
| Once I connect the fan to the connector, the device stops working. There is no higher voltage at the output end. The fan is just heating up and not rotating. | First, check if the fan power is too large or if the fan itself is problematic. The external fan current should not exceed 0.1A at 12V. |
| Use it to drive a 150W 36V LED. At first, the 4S lithium battery worked well, but about 5 minutes later, the LED was extinguished, the two fuses were burned. After the fuse was replaced, it burned immediately. No Output. | The switch tube may need replacement. |
| Regardless of whether the voltage is 5 volts or 32 volts, each fuse in it will pop up. | Check if the switch is broken. |
