TDK Lambda Model 71 Power Supply
The TDK Lambda model 71 Power Supply was created to help the specialists with the most demanding conditions in industry, labs, radio stations, and school to provide power to electronics and other equipment. This model includes 4 outputs. Output 1 has 0-500 VDC and 0-200 MA regulated, output 3 has 0-200 VDC, 0-50 VDC, bias output, output 3 has 6.5 VAC and 5A unregulated, and output 4 has 6.5 VAC and 5A unregulated.
The TDK Lambda 71 has a voltage between 0 to 500 VDC, a current between 0 to 200 MA (over entire voltage range), a regulation line of 0.15% or 0.3 V, a regulation load of 0.15% or 0.3 V, an internal impedance under 4 ohms, a ripple and noise under 5 millivolts, and a polarity where either positive or negative terminal may be grounded.
This model incorporates many fundamental controls for operation such as the Ac circuit breaker, the DC circuit breaker, the Voltmeter, the HV control, the BIAS Range, and the Output Current. In order to start the operation, the user should shut the AC and DC controls off, while the HV and BIAS controls should be in their counter-clockwise position. After everything is set, the user should plug the power wire into a source of 115V AC and connect the AC and DC loads to the output terminals.
If you are interested in this model and you want to read more about its controls, specifications, and highlights, you can view its manual, which is available on the ApexWaves.com website.
