SKU: CH12019Regulated DC Power Supply
Regulated DC Power Supply Unit provides a continuous DC output voltage with excellent load and line regulation at rated current. The voltage output is displayed on analog / digital meter. An internal protection is provided by a slow blow fuse at the primary and overload protection at the output. Power supply operates on 220V, 50Hz input. Please mention ‘A’ for analog and ‘D’ for digital meter at the end of part no. to specify the display required.

Resistance Box kit is an excellent device, which provides a very good learning technique in making different combinations of resistances, either in series or in parallel; or in both ways, to obtain the desired value of resistance for any circuit application. It consists of 10 resistors of equal values, i.e., 10? , 2 watts. These resistances are of ± 1% tolerance.
SKU: PH50438Resistance Box, Plug Pattern
All plugs are turned to a fine standard taper and are interchangeable. These are moulded in fluted plastic tops. The brass blocks are undercut and are fitted to a thick insulating plate. Heavy 4 mm brass terminals are used. Coils are non-inductively wound and are treated to be strain-free. Coil values are engraved on the plate and an infinity plug is also included. Accuracy ±0.5% for 0.01 to 0.05 ohm coils, ±1% for the rest.
