Seven fixed outputs: 5V, 6V, 9V, 12V, 15V, 18V and 24V
54.0 × 36.8 × 20.3mm body, weighing 48g
PCB-mount pins for installation inside the equipment
2 MOPP input-to-output isolation and 4,000VAC dielectric withstand voltage
Touch leakage current ≤100μA at 264VAC
Standby power ≤0.25W
85–265VAC input, with an operating temperature range of −25°C to +65°C

Models & Ratings

For a 12V design, the UES15D-SPA offers up to 1.25A. Choose the 24V version and the available current drops to 0.62A. Both belong to the same 15W series, so the voltage alone is only half the selection.

There are seven fixed-output versions in the table below, including 6V, 9V, 15V and 18V alongside the more familiar 5V, 12V and 24V options. Each is a separate version.

Mechanical Details

The UES15D-SPA brings the power supply inside your device, with four pins connecting it directly to the PCB. The body measures 54.0 × 36.8 × 20.3mm and weighs 48g.

Two pins take the AC input, and two carry the DC output. There is no separate DC cable or output plug in this configuration. The drawing below shows the pin positions and dimensions you need for the board layout.

Input Specifications

One UES15D-SPA input platform covers 85–265VAC, 47–63Hz. This includes common 100V, 120V, 230V and 240V mains systems within the stated input range.

Pay attention to the cold-start inrush when choosing the equipment’s input components. The listed 0.5A input current and 100A maximum inrush current describe different conditions; they should not be used interchangeably.

Input Characteristic	Specification
Input Voltage Range	85–265VAC
Frequency Range	47–63Hz
Input Current	0.5A at 100VAC
Inrush Current	100A max at 240VAC, cold start
Standby Power	≤0.25W

If your product has its own mains switch, fuse or input filter, include those components in the input design review.

Environmental & General

The air around the power supply can be warmer than the room outside your device. This is worth checking on an enclosed prototype, particularly if the UES15D-SPA sits close to a motor, display or another source of heat.

The catalog gives an operating range of −25°C to +65°C, but it does not show a load-versus-temperature curve on these pages. If your enclosure runs near the upper limit, confirm the permitted load for that temperature before settling on the design.

Operating Temperature	−25°C to +65°C
Storage Temperature	−25°C to +85°C
Operating Humidity	10–90% RH, non-condensing
Storage Humidity	10–90% RH
Operating Altitude	Up to 5,000m
MTBF	>100,000 hours, Telcordia SR-332 at 25°C

The listed >100,000-hour MTBF is calculated using Telcordia SR-332 at 25°C. It is a reference for reliability assessment—not a promise that an individual supply will run for that many hours.

Protection

The UES15D-SPA responds to overload, overvoltage and short-circuit conditions. The way it returns to operation depends on which protection has operated.

Overload	110–180% of rated output power; automatic recovery
Overvoltage	Catalog specifies 150% max of output voltage; input reset required
Short Circuit	Output trips and attempts to restart in hiccup mode

For overloads and short circuits, first remove the cause of the fault. Overvoltage protection requires the AC input to be reset.

The overload threshold is not extra output capacity. A motor or another load with a short starting surge still needs to be checked against the supply’s permitted operating conditions.

Safety Approvals

The UES15D-SPA has 2 MOPP isolation between the AC input and DC output. The catalog specifies 4,000VAC input-to-output dielectric withstand voltage and touch leakage current ≤100μA at 264VAC.

For your compliance review, ask for the documents covering the exact output version you plan to order. The catalog lists the following marks and standards.

EMC

The catalog covers both medical and ITE emissions and immunity references. For a medical equipment project, the medical column below is the starting point for reviewing the applicable EMC documents.

Item	Medical	ITE
Conducted Emissions	IEC/EN 60601-1-2; CISPR 11	EN 55032; CISPR 32
Radiated Emissions	IEC/EN 60601-1-2; CISPR 11	EN 55032; CISPR 32
Harmonic Currents	EN 61000-3-2, Class A	EN 61000-3-2, Class A
Voltage Flicker	EN 61000-3-3	EN 61000-3-3
Immunity	IEC/EN 60601-1-2	EN 55035; CISPR 35

The listed immunity tests include ESD, radiated RF, electrical fast transients, surge, conducted RF, magnetic fields, and voltage dips and interruptions.

Test the supply in the finished equipment configuration. PCB routing, mains wiring, the enclosure and connected cables can change the result from that of the power supply alone.

Common Applications

This 15W medical open frame power supply is intended for installation inside equipment. The applications below are starting points for OEM selection, with the output chosen to suit the complete device load.

For equipment with a motor or rechargeable battery, include starting demand and charging power—not just the consumption during normal operation.

Frequently Asked Questions

Is the UES15D-SPA suitable for my device?

First, what output voltage and current does your device need? Do you need any certifications, and which ones are required for your project?

If you already have a power supply, you can send us a photo of its label along with your device’s power requirements. That gives us a starting point for checking the output and certification requirements. Since the UES15D-SPA mounts inside the equipment, we’ll also need to know how much installation space you have.

With those details, we can check whether this model fits or whether another model would be a better choice.

I’m looking for a replacement. Can I keep the same PCB?

Possibly. Let’s compare the drawings before you make any changes.

The UES15D-SPA has four pins, with different spacing on the AC and DC sides. Matching the output is the first step; the pin positions and assignments also need to match your board. A photo of the existing supply is useful, but a drawing will give us a much clearer answer.

Would this be a good choice for a small pump?

With a pump, we’d look at the starting current as well as the current once it is running. The two figures can be quite different.

What pump are you using? Please send us its model number or a photo of the label. We may also need the starting-current figure, since that is not always shown on the label.

Can we order different outputs for different products?

Yes. Tell us the voltage and current needed for each product, and we can check which versions match.

For example, one product might need 6V at 2A, while another needs 9V at 1.5A. Both fall within the corresponding versions’ listed current ratings. They would be two different units, though—you cannot change one unit between those outputs.

How much room does it need inside our device?

The body is 54.0 × 36.8 × 20.3mm. Do you have a layout drawing showing where you want to put it? A sketch with dimensions is also useful.

We’ll look at the pin locations and the space around the supply as well as the body size. Please show any nearby components too, particularly anything that gets warm during use.

Can our device work and charge its battery at the same time?

How much current does it use while charging? That is the figure we need alongside the device’s operating current.

If your existing test only covers the device running with a fully charged battery, it may not show the highest load. Try to include the condition where the device is working and the battery is charging. The battery also needs its own charging circuit; that function is not built into the UES15D-SPA.
