Notes:

• 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
• 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47 uf parallel capacitor.
• 3. Tolerance: includes set up tolerance, line regulation and load regulation.
• 4. Derating may be needed under low input voltages. Please check the derating curve for more details.
• 5. The ambient temperature derating of 5°C/1000m is needed for operating altitude greater than 2000m (6500ft).
• 6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to "EMI testing of component power supplies." (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf).
• 7. R type efficiency slightly less than the Blank type, according to the actual measurement.
• 8. Inrush current parameter has 10% tolerance.
• 9. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.
• 10. Some models or factory may not have the BIS marking, please contact MEAN WELL's sales for more details.

Block Diagram

The block diagram illustrates the internal signal flow of the UHP-200 series power supply. Input power (I/P) first passes through an EMI Filter & Rectifier, followed by a PFC Circuit. This is then fed into the Power Switching stage, which is regulated by a Control circuit. The output is processed by Rectifiers & Filter to produce the final DC output (+V, -V). The diagram also shows a Detection Circuit monitoring Over Temperature Protection (O.T.P.), Over Load Protection (O.L.P.), and Over Voltage Protection (O.V.P.). Optional DC OK Function and Redundant Function are indicated. The switching frequencies are noted as PFC fosc: 100KHz and PWM fosc: 90KHz~110KHz.

Derating Curves

Derating curves illustrate the relationship between rated current percentage and ambient temperature for optimal performance. Three primary curves are presented:

• Ambient Temperature (°C) vs. Rated Current (%): Shows derating for "for other" models and "for 55V" models under general conditions.
• Ambient Temperature Without Aluminum Plate (°C) vs. Rated Current (%): Details derating for various input voltages (100Vac, 230Vac) and model types ("for 55V", "for other"), indicating reduced performance at higher temperatures without proper heat sinking.
• Tcase (°C) vs. Rated Current (%): Depicts the derating based on the case temperature, showing limits for "for 55V" and "for other" models, with a maximum operating range extending to 90°C.

Note 5 specifies that ambient temperature derating of 5°C/1000m is needed for operating altitudes greater than 2000m (6500ft).

Static Characteristic

The static characteristic graph shows the relationship between Input Voltage (V) at 60Hz and the Load (%). It indicates that the power supply operates efficiently across a wide input voltage range from 90VAC to 264VAC, maintaining full load capacity (100%) within this range.

Function Manual

1. DC OK Signal

The DC OK signal is an optocoupler output that indicates the power supply's output status. When the optocoupler's C-E pins conduct, the PSU is turned on and the DC OK signal is active (DC ok). When the optocoupler's C-E pins are open, the PSU is turned off, and the DC OK signal indicates a DC fail. The optocoupler has a maximum rating of 15Vdc/10mA resistive load.

2. Redundant Function

The UHP-200R models feature a built-in redundant function, allowing two units to be connected in parallel for increased reliability. In parallel operation, the total load should not exceed the rated power of a single PSU.

Mechanical Specification

The UHP-200 series has a slim profile with dimensions of 194mm (Length) x 55mm (Width) x 26mm (Height). The unit case number is 249B, with a tolerance of ±1mm.

Installation

1. Operation with Additional Aluminum Plate

To meet the derating curves and static characteristics, the UHP-200 series must be installed onto an aluminum plate or a cabinet of equivalent size on the bottom. The suggested aluminum plate size is 300mm x 300mm. For optimal thermal performance, the aluminum plate should have an even and smooth surface, potentially coated with thermal grease. The UHP-200 series must be firmly mounted at the center of this plate. Mounting is done using M3 screws (4 required).
