Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. 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 )
- 5. Mounting holes M1 and M2 should be grounded for EMI purposes.
- 6. Heat Sink HS1,HS2 can not be shorted.
- 7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the PT-65B in an industrial control system that needs 5V and plus/minus 12V rails?
Yes, the PT-65B is built for constant-voltage applications and combines 5V output with 12V and -12V rails in one unit. Its 63.5W rating and 5.5A output current on the 5V rail make it suitable for control, interface, and signal-processing equipment that needs those three voltages from a single power supply.
Is the PT-65B a good fit for embedded test equipment or bench electronics with mixed low-voltage rails?
It can fit embedded and bench systems that need 5V together with 12V and -12V outputs. The wide 90-264VAC input range also helps when the same equipment may be used across different AC mains conditions.
Can the PT-65B support automation hardware that runs mostly on 5V but also needs bipolar analog rails?
Yes, this model is intended for applications where a regulated 5V rail is the main load and 12V and -12V rails are also required. With 63.5W total power and 5.5A available on 5V, it suits compact automation assemblies that combine digital logic and bipolar analog circuitry.
How does the PT-65B compare with the other PT series sibling models?
On the PT-65 series sheet, the PT-65A is 60W with 5V 5.5A, 12V and -5V outputs; the PT-65C is 65W with 5V 5.5A, 15V and -15V; and the PT-65D is 68W with 5V 4A, 12V and 24V. The PT-65B itself is 63.5W with 5V 5.5A, 12V 2.5A and -12V 0.5A, and its product name identifies it as the 5V, 12V, -12V version.
Is the PT-65B suitable for outdoor or harsh-environment use?
The provided specs show an operating temperature range of -10°C to +60°C, with output derating at higher temperatures per the derating curve, but they do not list an IP rating. That means environment suitability should be checked against the -10°C to +60°C range and any required ingress protection should be handled at the system level.
