System-based dependencies
The following question pops again and again: How many electronic
ballasts/energy-saving bulbs can connected device? such
cases, there decisive answer, despite all efforts. accordance with
the traffic light principle, the bars are shown from top bottom the
colours dark green through yellow dark red. addition, the manufacturer the switching device rarely
notified any changes the switching technology the electronic
ballast.
strain the contact material relay certain degree.
Such diversity products ultimately leads the inability manufac-
turers the switching device provide concrete information, even
when questioned about the connection options specific electronic
ballast. Details are regulated corresponding EU
regulations for each product group with regard their energy con-
sumption values. Use power relay, for example, for higher currents and longer
switch-on times. While state-
ments can still made regarding the maximum permissible size the
compensation capacitor and thus the maximum permissible load with
parallel-compensated loads, itisgenerally longer possible with elec-
tronic ballasts and energy-saving bulbs.
They include, among others:
-
The conditions the supply mains (hard soft mains)
D Soft mains:
great inner resistance the mains, lower switch-on currents
D Hard mains:
small inner resistance the mains, high switch-on currents possible
-
Switch-on time based current value sine wave,
D Sine-wave zero crossing:
ideal, hardly any contact load
D Sine-wave vertex:
poor, maximum switch-on current
-
is always switched the positive half-wave, for example
D Material migration contact material always goes the same
direction
D Quicker failure the contact
These system-based factors prevent even the relay manufacturers from
providing concrete information the connectible load relay.

protected against disassembly without key. The directive lists various product groups, which are evaluated
according certain criteria. Here, each electronic
ballast/energy-saving bulb may have completely different switch-on
properties.

The locking bit can adjusted for half-cylinder profiles pressing in

Energy efficiency classes 2010/30/EC
The directive 2010/30/EC contains general conditions for classifying
products. this case, the green
level indicates the most favourable consumption values.

Please comply with the switch-on peak currents with all capacitive
loads. After actuation, the key can be
turned back the exit position and pulled out.
These are factors which are system- and application-specific and are not
