Power supply is no problem even for DC12V, WEC200 or Electric Lock.
Please note
the
current is not more than
3A
for electric lock particularly. You may use DC12V right now if your
survey is available. Unfortunately, if only DC24V is workable for your electric lock, you are still able
to use your own electric lock with DC24V separately. As for model WEC200, it accepts the power
supply of DC12V only. Definitely, two GND should be connected together, and then the whole
system works actually.
(Refer to the illustration of this chapter
– separateness way of power
supply).
If your electric lock supports AC,
please note
the voltage volume rates at 1A/125VAC for the
contact of relay, so the current is not more than
1A
. Some countries accept 220VAC~240VAC only
for their local voltage, we hence suggest that you may use an external relay. Let the relay of WEC200
control your external relay unaffectedly.
Power Supply
The power supply of WEC200 adopts DC12V. If only one power supply is available for WEC200
and electric lock together, moreover current of the electric lock is I
LOCK
fortuitously, you have to
adjust 2*I
LOCK
at least for the power supply. WEC200 itself is causative, which its consumable
current stays at 150mA. The running electric locks on the market exceed in this value widely. In
order to prevent the power consumption is incapable load under the status of activation or
deactivation, supernumerary power supply is necessary, which lose voltage in a second and
re-activate WEC200 again.
(If you discover this status is appeared when testing, please use other
power supply) (Refer to last illustration)
We strongly suggest to use separate power supply for
electric lock.
All above is just mentioning only one electric lock is using. If using two electric locks, the power
supply should be loaded by 4*I
LOCK
at least.
For the sake of safety, power supply device should be mounted at a safe location.
Door Open Sensor
Two kinds of door open sensor are normally-opened and normally-closed dividedly. N.C. is rather
popular on the market, which is proper to connect the terminals of INPUT1 or INPUT2 for WEC200. So
WEC200 is working the current status for the entrance.
