FAQs
for LPP300 Series 300 W Single Output Low Profile Industrial and Medical Grade PSU
The LPP300 series is available in three single-output versions: 12 V, 24 V, and 48 V DC. Each model supports approximately ±5% output trim, allowing engineers to fine tune the voltage for application requirements or to compensate for cable losses.
To reach the full 300 W output rating, the LPP300 typically requires forced-air cooling. With sufficient airflow, the supply can deliver its maximum rated power. Under natural convection or reduced airflow, the available output power is lower, so fan cooling is recommended for full-capacity operation.
The specified operating range is -20 °C to +70 °C ambient. Output derating is required at higher temperatures, with derating beginning above approximately +50 °C. This helps maintain safe thermal performance and long-term reliability.
The series is designed to meet IEC 60601-1 for medical safety and IEC 62368-1 for industrial/ITE applications. It also supports EN 55011/EN 55032 Class B emissions and IEC 60601-1-2 4th Edition EMC requirements, helping simplify compliance in sensitive medical and industrial equipment.
Yes. The LPP300 series supports Type BF medical application requirements, making it suitable for systems such as patient monitors and imaging equipment where stringent patient leakage limits are important. Final compliance still depends on the design of the complete end equipment.
Each model includes multiple built-in protection functions, including over-voltage protection, over-current and short-circuit protection, and overload protection. These features help protect both the power supply and the connected load during abnormal operating conditions.
Yes. With a height of just 0.75 inch (19 mm) and a 3 inch x 5 inch footprint, the LPP300 is well suited to compact embedded designs and can fit comfortably inside 1U rack-mounted systems, subject to the overall mechanical and thermal design.
Yes. The LPP300 includes a dedicated 12 V auxiliary output intended mainly for powering an external cooling fan. This helps simplify thermal management, but it is not intended to function as a standby logic supply.
Typical applications include medical imaging systems, patient monitoring equipment, infusion pumps, and test and measurement instruments. It is a strong fit wherever compact size, low EMI, and dependable power delivery are essential.
An open-frame design means the power supply is provided as a bare internal board without its own external enclosure. It is intended to be mounted inside the end system, so the equipment manufacturer must provide the necessary mechanical protection, insulation, and safe integration within the final product.
