Customer Questions
Does the RT-65B support universal input voltage without manual switching?
Yes. The RT-65B accepts 88 to 264VAC at 47 to 63Hz and uses auto-switching SMPS topology, so no manual voltage range selection is required.
What output voltages and currents does the RT-65B provide?
The RT-65B provides three outputs: +5V at 5A (Channel 1), +12V at 2.8A (Channel 2), and -12V at 0.5A (Channel 3), for a combined rated output of 64.6W.
What protections are built into the RT-65B?
The RT-65B includes built-in short-circuit, overload, and overvoltage protection, and is rated to withstand a 300VAC surge input for 5 seconds, per the manufacturer's specifications.
What are the physical dimensions of the RT-65B?
The RT-65B measures 5.1 inches long by 3.9 inches wide by 1.5 inches high. Confirm enclosure fit against these dimensions before installation.
What agency approvals does the RT-65B carry?
Agency approvals listed by Jameco for the RT-65B include UL, CUL, TUV, CB, CE, EN, and EAC. Refer to the manufacturer's compliance documentation for specific standard details.
Customer Concerns
Will the total output power be sufficient for my application?
The RT-65B is rated at 64.6W total output across all three channels. Before selecting this unit, verify that the sum of your load requirements across the +5V, +12V, and -12V rails does not exceed the manufacturer's rated output per channel and total power limits. Consult the datasheet for channel loading guidelines and derating curves.
Is this power supply suitable for continuous-duty operation?
The RT-65B is an enclosed switching power supply designed for use in industrial and ITE applications. For continuous-duty use, verify ambient temperature conditions against the -25°C to 70°C operating range and review any derating guidance in the manufacturer's datasheet to confirm suitability for your specific installation.
