A precision decade inductance box suitable for filter design, general purpose substitution, DC to DC converter design and calibration of measuring instruments.
The 1053 is housed in a fully screened robust metal case making it durable and compact. It is a practical instrument that is simple operation, suitable for use in electronics, production, R&D, or as a calibration tool in the lab or field.
Inductance is set by four easy-to-read dials that are divided into 4 decades. These provide 1 mH, 10 mH, 100 mH, and 1 H steps. The maximum setting is 11.11 H.
The unit features custom wound, high permeability ferrite core inductors that ensure insignificant influence from external magnetic fields and maximum stability.
- 1 mH to 10 H
- In-line readout
- 3 % accuracy
- High stability
- Safety terminals
- Fully screened
- Robust and portable
Inductance is selected by dialling the value required using the rotary switches. This enables precise setting with a clear unambiguous indication.
Each decade is scaled from 0 to 11. This allows a convenient overlap of the set values.
The 1053 connections are via safety terminals that are compatible with standard plugs, 4 mm shrouded plugs, bare wires, and spade terminals.
These terminals are specifically designed with safety features including limited opening distance and a raised flange around the metal connection surface. This ensures that the clearances are sufficient to make the exposed metal parts touch-proof.
