A robust 12 V switched power supply using traditional step-down transformer technology, ideal for lab use. It provides smoothed AC and DC outputs via front panel sockets, with overload protection and a thermal trip. The voltage selector disconnects output when adjusted to protect contacts and can be locked using a front panel Allen screw. Housed in a durable, powder-coated case with a carry handle. Suitable for up to 5 A max (4 A continuous). DC output is capacitor-smoothed with increased ripple at higher currents. Four units fit in one storage tray.
