HLK-1D0505A 5V 1W 200mA DC to DC 88% transfer efficiency power supply modules replace B0505S-1WR3

Product performance:

1. Isolation between input and output is required (isolation voltage 1500VDC or less)

2. No-load input current as low as 5mA

3. The voltage of the input power supply is relatively stable (voltage change range ± 10% Vin)

4. Operating temperature range: -40 ~ + 85 Degree

5. Output short-circuit protection, low requirements for output voltage stability

6. Low ripple / noise (20MH bandwidth): 30mVp-p (typ)

7. International standard pins, PCB board in-line installation

8. Adopting high-quality environmental protection waterproof and thermally conductive adhesive potting, moisture-proof, vibration-proof, meet the waterproof and dustproof IP65 standard

9. High reliability, long life design, long continuous working time

Environmental conditions:

Working environment temperature: -40- + 85 Degree

Storage temperature: -40- + 80 Degree

Relative humidity: 5-95%

Cooling method Natural cooling

Atmospheric pressure: 80-106 Kpa

Vibration coefficient: 10 ~ 500Hz, 2G10min./1cycle, 60min.each along X, Y, Z axe (Meet the requirements of secondary road transportation)

Product application considerations:

1.Input requirements: Ensure that the output voltage fluctuation range of the power supply does not exceed the input requirements of the DC / DC module itself, and the output power of the input power must be greater than the output power of the DC / DC module

2. Overload protection: Under normal operating conditions, the output circuit of this product has no protection function against overload conditions. The easiest way is to connect a resettable fuse in series at the input, or add a circuit breaker to the circuit

3. The capacitance of the external capacitor at the output should not be too large, otherwise it will easily cause overcurrent or poor startup when the module starts
