UPS PIco HV3.0 Bi Stable Relay
The
UPS PIco HV3.0 HAT
can be equipped with Bi Stable Relay with single coil. This
Relay is standard offered with version UPS PIco HV3.0 HAT Plus, it can be also ordered
separately and added to the UPS PIco HV3.0 HAT Stack/TopEnd. In both cases this
Relays is not mounted on the PCB and user need to do it by himself. The assembly
(soldering) of the Bi Stable Relay on the UPS PIco HV3.0 HAT PCB it is very easy task
and can be done by anybody using simple soldering iron. However it is also possible
that this assembling can be ordered to be done by us, if customer order directly on
the eshop or any other eshop that offer such service.
The main benefit of the Bi Stable Relay is the power consumption. The Bi Stable Relays
consume power only when switching from one state to another. All other times are
not consuming power at all. So, we called it Zero Power Relay. Driving of such relays
are little bit more complicated than the usual ones, however user not need to care
about that as electrical drivers are assembled on and offered with each UPS PIco HV3.0
HAT PCB. Each Bi-Stable Relay does not have states
NO
(Normal Open) or
NC
(Normal
Close), it has
Reset
and
Set
state instead. By switching of the Bi Stable Relay, user
changes the state from
Reset
to
Set
and vice versa. User should know that If Bi Stable
Relay change their status
Reset/Set
will stay on it (also when power will be completely
removed) until new switch commend will be send. If Bi Stable Relay receives one
command
Reset
or
Set
, sending multiple times of the same will not change anything.
To change status must be send opposite one i.e. if s
Reset
, the opposite one is
Set
.
