5. Maximum number of locks on 1 Power Supply
There is not a fixed number of locks that can be connected to 1 Power Supply, it really depends on how the lockers
are used, how these are wired and if the emergency key can be used.
Below calculations are all based on Watt so it’s easy for calculations. The maximum number of locks connected to 1
terminal is 256.
What can influence the power consumption of a Lock:
 The colour of the status led.
We use an RGB led, so if you want a white colour, all 3 led’s will be active, for Red, Green or Blue only 1 will
be active.
 The brightness of the status led.
The brightness is configurable in the Releezme Lock Profile between 0% – 100%
 The brightness of the internal lighting.
The brightness is configurable in the Releezme Lock Profile between 0% – 100%
It’s only active when the door is open.
 Activation of the Coil.
Usually a lock has only an active coil for a few seconds (let’s say 3-20 seconds). Once a door has been
opened the Coil will be deactivated.
 USB Charging.
If a device is using the USB port(s) to charge, it can take up to 1000mA (5 Watt).
USB charging is disabled by the lock software while the Coil is active.
 Emergency Key (Block 1 or Block 2 signal on the LBC 3.0 terminal).
This can activate x number of locks.
If the signal is active for more than 15 minutes, the Locks will ignore the signal and deactivate the Coil (USB
will then be activated again).
The Locks parts have the following power consumption:
 0.18W Basic electronics V3
 0.28W Basic electronics V3+ series
 0.13W Red, Green or Blue (white is 0.31W)
 0.54W Internal lighting (active when door is open)
 4.00W Coil
 5.00W USB charging
The firmware in the lock also takes care of some power savings:
 When the USB charging is active and the door is open, the internal LED has a maximum brightness of 50%
 When the Coil is active, the USB charging is disabled
 When the door is open, the RGB status led is dimmed to prevent that people look into a bright light.
 The software switches the Coil off when the door is opened
 If the Block signal is active, the USB charging will be disabled
Above means for the V3 locks (All V3+ locks use 0.1W more):
 0.31W Idle power consumption of the V3 lock (1 status led and closed door)
 0.85W Open power consumption of the V3 lock (1 status led and open door)
 4.56W Max power consumption of the V3 lock (3 status led, closed door and active Coil)
 5.56W Max power consumption of the V3 lock (3 status led, closed door and active USB)
The Power Supplies (PSU) applied are available in 2 sizes. The large PSU can supply 432 Watt, the small PSU can
supply 185 Watt.
