With charge indicating system 2 volts 45 AH on 20 Hrs rate in plastic container.

For charging batteries. In metallic case with ammeter, switch for 6V/12V charging,with output fuse and indicator lamp. Complete with battery terminals and main cable. Operates on 230 Volts 50 Hz.

A spring arm , press knob, contact stud and a connecting strip with two 4 mm. terminals on plastic base of 100 x 60 mm. size.

These meters are developed to teach easily constructional features of permanent magnet moving coil type. Movement is fitted in transparent wooden box and internal electrical connection are made visible. These meters can be used for demonstration and also for actual measurements.

Pocket size multimeter is self-contained portable test set that measures a wide range of Voltages, Currents and Resistances. This is an indispensable instrument for servicing and maintenance of electronic equipment, radio and television. The meter is so designed and its movement is heavily damped to avoid damage to the meter movement.

Low voltage, moulded base with plated contacts and screw connections.

ALSO AVAILABLE MOUNTED ON BAKELITE BASE WITH TERMINALS

Low voltage, double pole double throw, may be used as changeover switch with appropriate connections, moulded base with plated spring metal contacts and screw connectors.

ALSO AVAILABLE MOUNTED ON BAKELITE BASE WITH TERMINALS

Two brass blocks with 4mm insulated terminals are mounted on a moulded base, an accurately tapered plug with a fluted top fits into the tapered hole between the two blocks, ensuring very low contact resistance.

With three brass blocks, each with a 4mm insulated terminal and two standard tapered plugs to fit the two holes between the blocks.

POWER SUPPLY, Continuously VARIABLE, 25V

Gives continuously variable a.c. and d.c. outputs upto 10 A for a.c. and 8 A for d.c. A meter is provided to indicate both a.c. and d.c. voltages. An internal fuse is provided for input and a resettable cut-out for output. With detachable 1.5 metre mains lead.

Specifications:

Mains Input :220-240 V a.c. 50/60 Hz

Output Voltages :0 to 25 V a.c. and unsmoothened full wave rectified d.c.

Output current :10 A maximum a.c.:

8 A maximum d.c.

Voltage Selection :Rotary continuously variable transformer operated by a large knob on front panel.

Metering:A.c. and d.c. output voltages by a moving coil meter with selector switch to select a.c. or d.c.

Circuit protection :Mains input 3 A internal glass fuselink. Output is protected by a resettable cut-out.

Output terminals :Colour coded 4 mm sockets.

The unit provides a continuously varible E.H.T output from o to 5 kV d.c. with a low voltage output of 6.3 volt d.c. and is ideal for vacuum tubes etc.

This unit uses a low voltage transistor inverter circuit and E.H.T. transformer. The high a.c. voltage is rectified and smoothened. A meter calibrated 0 t0 5 kV is connected to control the output voltage.

Output :

E.H.T.-0 to 5 kV d.c., continuously variable. Terminal output voltage indicated by meter. Max short circuit current is safely at 3 mA. A heater supply 6.3 V a.c. at 4 A is fully isolated & insulated for 5 kV.

Protection :

Mains 500 mA antisurge fuse, Output overload protected, E.H.T. max current limited to 3 mA.
