DC to AC Inverters
A range of highly efficient 12V DC to 230V AC inverters intended to power a wide range of  mains equipment from a 12V lead acid battery, including small power tools, laptop computers etc as well as use as an emergency power supply. They are compact and feature protection against low/high input voltage, temperature, overload and short circuit, as well as a low battery alarm. A standard 13A mains socket is provided.

150W DC/AC inverter with a cigarette lighter plug for the 12V input
Order Code PSREINV3800 £49.95

5V 1A Regulated Power Supply
A sturdy regulated power supply delivering 5V at a maximum of 1A. Ideally suited to educational applications in both primary and secondary schools. The output is delivered via colour coded 4mm terminals and is monitored by an LED which indicates normal/short-circuit conditions by its colour. The unit is short-circuit protected. An internal control allows the output to be preset within the range 5 to 8.5V.

The supply is enclosed in a sturdy fully earthed steel case and is supplied complete with mains lead and instructions. Dimensions 120 x 110 x 150mm.  Order Code PSBPSU1725 £79.95

Dual Rail 100mA Regulated Supply
A rugged power supply offering dual rail voltage output with twice the current output usually available in units of this type. Output is 15-0-15V at 100mA per rail. The unit is designed for powering operational amplifiers and features short circuit protection and output status monitoring via tricolour LEDs. Output is via colour coded 4mm terminals. The supply is enclosed in a sturdy fully earthed steel case and is supplied complete with mains lead and comprehensive instruction manual. Ideal for laboratory and educational use.

0-15V Laboratory Power Supply
A professional laboratory power supply with LCD display with backlight for voltage and current and current and voltage adjustment
Fuse protected, with a front panel made from plastic, all others made of steel. White/grey in colour with IEC1010 output connectors.
Output Voltage 1.2 - 15V adjustable, Output Current 0-3A, Dimesions 215x155x95mm

8A AC/DC Power Supply
A robust power supply that will deliver outputs of 2, 4, 6, 8, 10 or 12 volts via two pairs of 4mm terminal posts. The output voltage is selected by a front panel rotary switch. A locking key operated switch mounted on the front panel selects either AC or DC output. The maximum available output voltage, indicated by a row of red LEDs, may be set by inserting a screwdriver into a recessed control on the underside of the unit. Short circuit and overload protection is provided by using an internal automatically resetting cutout.

6A AC/DC Power Supply
This power supply offers AC voltages of 2, 4, 6, 8, 10 or 12V and capacitor smoothed (10,000uf), DC voltages of 1, 4, 7, 10, 13 or 15 volts. Separate AC and DC colour coded terminals are provided and AC and DC voltages may be used simultaneously up to a maximum combined load of 6 amps. An earth terminal is also provided. The voltages are selected by a six position key switch, the key is removable in any position. The output voltage is monitored by a sophisticated system which detects overloads and short circuits and cuts power to the terminals under these conditions.

30V 2.5A Regulated Power Supply
A high quality fully regulated power supply capable of supplying up to 30V at a maximum of 2.5 amps with additional fixed 5V and 12V outputs at 500mA, ideally suited to laboratory test and educational environments. Voltage and current outputs are individually shown on liquid crystal displays. The output voltage is continuously adjustable via a single control from 0 to 30V DC. Output current limiting is fully adjustable up to 2.5A. The 30V output is terminated with 4mm colour coded terminals, the 5V and 12V outputs are terminated via a spring loaded colour coded terminal block.

220V AC to 12V 5A Linear Power Supply for powering car and caravan accessories
A robust power supply with a carrying handle, mains on/off switch and accessible front panel mounted fuseholder.
The 12V output is supplied through a cigar / cigarette lighter socket which accepts cigar lighter plugs which are usually found on equipment designed to run from a 12V car battery.
