| with resistive loads ａnd inductive loads as Test Power Supply for testing the breaking capacity ａnd the behaviour during normal use of switches resp. of plugs or socket-outlets for household ａnd similar purpose with resistive-load rated currents up to 16 A, for tests with alternating voltages, | |
| according to | IEC 60669-1 | :2007-01 § 18 ａnd § 19.1, | |
| | IEC 60884-1 | 2006-07 § 20 ａnd § 21, | |

| Information N 03 |  | |
| Fundamental design | |
| A power supply consists of the power unit which provides the adjustable test voltage, as well as the resistive load units ａnd the inductive load units. | |
| Operation as agreed | |
| The power supply is primarily designed for | |
| ● | testing the breaking capacity and | |
| ● | testing the behaviour during normal use | |
| for operation together with PTL Actuating Units of the series F 55. For this, both components are connected by means of a connecting lead with multiple connector. By this a reciprocal cut off of the components is ensured, in normal test duty as well as in case of fault, caused by the specimen or by one of the components. | |
| It is possible to operate the specimen manually or to connect an other than a PTL Actuating Unit, but then, a cut off of the test voltage at the specimen is not ensured, ａnd thus safety of staff is endangered. | |
| Further employment | |
| Further possible applications may be considered. For example checking electric lines ａnd fuses is possible. Or an other than a PTL Actuating Unit can be connected. | |
| The resistive ａnd the inductive load units are floating. Therefore, they can be employed arbitrarily ａnd also independently of the main transformer. | |
| Design: |  | |
| Trestle of rigid steel tubes with feet, suitable for transportation by forklift, slide bars for the slide-in modules, bottom, side walls ａnd rear wall covered by steel sheets, lower part of the rear with intake opening(s), top with exhaust opening(s), both prepared for mounting air ducts, slide-in modules of rigid steel bars, front panels of anodized aluminium, steel parts structure varnished papyrus-white with stone-grey highlights. | |
| For connection to three-phase 3 x 400 V / PE 50 Hz, mains connection cable with plug ａnd inclusive fitting socket-outlet for wall fastening. | |
| Available models: | |
| One phase model, suitable for testing one single phase specimen (see top Fig.): | |
