The Mitsubishi Q61SP is a slim-type power supply unit that sits in the base mounting slot of a Q3□ SB base. It delivers a regulated 5 VDC output rated at 2 A from an AC input of 100 to 240 V (-15% to +10%) at 50/60 Hz ±5%. The built-in fuse is user-replaceable, and the unit includes an LED indicator that shows green under normal operation and turns off on fault.
Protection and isolation
Overcurrent protection kicks in at 2.2 A or more on the 5 V rail; overvoltage protection clamps between 5.5 and 6.5 V. The unit withstands input-to-ground and output-to-ground at AC 2300 V for 1 minute, and insulation resistance measures 10 MΩ or more at 500 VDC. Inrush current is limited to 40 A within 8 ms.
