The LPP200 series 200 W open-frame power supplies are designed to meet the needs of modern medical and industrial equipment manufacturers who face tight space constraints. With a slim 0.75-inch profile and a standard 2″ x 4″ form factor, these AC-DC units provide substantial power output without bulk. They are available in 12 V, 24 V, and 48 V single-output variants, allowing engineers to choose a model that best matches their system’s DC rail requirements. All versions carry full medical (IEC 60601-1 Type BF) and industrial/ITE (IEC 62368-1) safety approvals, streamlining compliance for patient-connected devices and industrial systems.
A high efficiency of around 90% minimises waste heat, which is crucial for reliability in confined spaces. Thanks to excellent EMI/EMC performance (Class B emissions and immunity to IEC 60601-1-2 4th Ed.), the LPP200 series integrates smoothly into sensitive environments like hospitals. Typical use cases include patient monitors, medical displays, infusion pumps, laboratory instruments, and compact industrial controllers—any application where a compact 200 W power supply is needed without compromising performance or safety.

FAQs
for LPP200 Series 200W Open Frame Low Profile PSU
The LPP200 series offers three single-output models: one for 12 V DC, one for 24 V DC, and one for 48 V DC. These variants share the same 200 W power capability and physical design, differing only in their output voltage and current ratings. For example, the 12 V model can supply up to about 16.7 A, whereas the 48 V model provides roughly 4.2 A (both can deliver ~200 W with adequate cooling). This range of outputs lets you choose a supply that matches your system’s required voltage rail without altering the form factor or performance benefits.
Yes, but with limitations. The LPP200 is designed to provide up to 200 W when proper airflow is applied (for instance, using an external fan). In purely convection-cooled mode (no fan), it can still deliver substantial power, but not the absolute maximum—you would typically need to derate the output at higher ambient temperatures. The unit includes an onboard 12 V fan output specifically so you can power a small fan for cooling. By adding a fan, you ensure the supply stays within temperature limits and can reliably output the full 200 W. Without a fan, it’s suitable for lower power operation or intermittent high loads, provided the temperature remains within safe limits.
Absolutely. The LPP200 series is fully certified to medical safety standard IEC 60601-1 (Edition 3.1) and carries a Type BF (Body Floating) rating. This means it has the required isolation, low leakage currents, and risk mitigations to be safely used in patient-connected medical equipment such as patient monitors or diagnostic devices. In addition, it is certified to IEC 62368-1 for IT and industrial equipment. Using an LPP200 supply can simplify your product’s safety approval process since the PSU already meets the key standards for both medical and industrial applications.
Yes. The LPP200 supplies are designed to meet Class B EMI emission limits, which are the stricter standards typically required in residential and medical environments (more stringent than Class A). They also comply with the IEC 60601-1-2 4th Edition EMC standard, meaning they have robust immunity to electro-magnetic disturbances commonly present in medical settings (such as RF interference from other equipment) and low emissions that won’t interfere with nearby sensitive devices. This high level of EMI/EMC performance makes the LPP200 series well-suited for hospital and laboratory use, as well as industrial environments where electronic noise can be a concern.
Each LPP200 model is rated for operation from -20 °C up to +70 °C ambient temperature. However, like most power supplies, it requires derating above a certain temperature – typically above +50 °C you would gradually reduce the maximum load to avoid overheating. The ultra-low-profile design still manages heat effectively due to high efficiency (~90%), but if your application runs hot or near the upper temperature range, using the 12 V fan output to add a cooling fan is recommended for full power operation. The unit’s robust design and quality components ensure reliable performance across its temperature range and under varying humidity or altitude conditions that are normal for medical and industrial environments (within the limits given in the datasheet).
The LPP200 power supplies come with a full set of protection circuits. They include over-voltage protection (OVP) to prevent the output from exceeding the set voltage significantly, short-circuit protection to safely limit current and avoid damage if the output is shorted, and overload/over-current protection (OCP) which will reduce output or shut down the supply if you draw more than the rated current. These features operate autonomously and reset either automatically or via power cycling once the fault is cleared. Thanks to these protections, both the power supply and the devices it powers are safeguarded against common fault conditions, improving overall system reliability.
The primary advantage of the LPP200 series for compact device design is its size and power density. With a footprint of only 2 × 4 inches and a slim 0.75 inch height, it can be tucked into tight spaces inside your product. It delivers about 33 W per cubic inch, which means you get a full 200 W output in a fraction of the volume that older power supplies would require. This high power density allows designers to miniaturise their end equipment or include additional functionality in the same space. Additionally, because it’s an open-frame design, it’s lightweight, and you have flexibility in how to position or cool it within the device. In short, using an LPP200 PSU enables more compact, portable, or densely-featured systems without sacrificing the power output needed.
