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,

|
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.
