Application Area:Amplifiers and Pre-Amps (400's)Product Area:Main Group DC-1GHzFrequency Range:45Hz-15kHzTuning:Internal Signal SourceInterface:4mm socketsOther:Power Source simulationEMC Item No:401
This amplifier has an integral LF signal source module with an analogue frequency dial which can be varied from 45Hz to 15kHz. It's essentially a power frequency source simulation. The distortion is less than 1%. A variable output control feeds the main amplifier which in turn produces an output from 0-125Vrms or switched to give 0-250Vrms. A high degree of negative feedback between the M.O./P.A. keeps the wave distortion to a minimum. The output can tolerate a reactive load with a PF of between 0.7-1 and with changes from no load to full load within seconds. Thus the amplifier is ideal for testing such devices as motors; rectifiers; switching relays; chokes; capacitors; fluorescent lamps; synchronisers and the general testing of most magnetic circuits. General applications: Whenever devices have to be run from a simulated AC supply employing both frequency shift and changes in voltage (surge) such as MIL-STD-704B then this amplifier has an application.
General Specification:
Power 400VA.
O/P Impedance: 4 ohms.
Connectors: 4mm skts.
Power Req: 220vac 50Hz. (Variac supplied to keep supply voltage down to 220VAC).
Size: 46cm x 48 cm x 23cm. Weight: 45 kg.
