This is not an "electronic transformer for halogen bulbs", rather:
PS-65 SERIES - 65W SINGLE OUTPUT AC-DC OPEN FRAME POWER SUPPLY
The output is DC, and this is what is usually called SMPS. The output is DC, and the 65kHz refers to the oscillation frequency.
You could relatively easily add high-speed diodes (I guess UF400x would do) and the rest of the necessary components, transforming an "electronic transformer for halogen bulbs" into an SMPS device.
But that would be superfluous - HF AC can perform the task (heating direct heated tubes) more efficiently and hum/noise free. Definitely a better solution to the SMPS - the latter should be compared to other DC solutions.
