Safety
The external flexible cord of this product cannot be replaced; if the cord is
damaged, the product shall be scrapped.
When the transformer is connected in a wrong way (short circuit) or it
encounters an overload, the "Off-led" will blink to signal the installer. Above a
certain level of overload the transformer will shut down and reset itself when the
touch pad is activated manually. This procedure will loop until the connection has
be done right or the load is reduced to an acceptable level.
This product has triple protection. It's based on 3 mechanisms:
1. Current monitoring by software,
2. Voltage monitoring after PTC's (3x 9A PTC),
3. Transformer temperature monitoring (thermal resettable fuse inside toroid
transformer).
The software protection is based on one true-RMS current measurement and two
voltage measurements. If the external load is increased, the following levels are
reached for SMART HUB-150:
Detection levels calibrated for each product at 100% of nominal load (150
•
VA).
If the current exceeds 120% for a few seconds (>180VA), the "off-Led"
•
(around the on/off-button) starts blinking slowly until the load is
decreased below 120%.
If the current exceeds 140% for a few seconds (>210VA), the relay is
•
switched off and the "off-Led" starts blinking fast until the on/off-button is
activated (reset after overload).
If the current exceeds 200% (>300VA), the relay is switched-off
•
immediately until the on/off-button is activated (reset after short-circuit).
If the customer resets too many times during overload/short-circuit the 3
•
PTCs on the connection PCB become hot and the output voltage will
become too low, which is measured by the software. The output will be
disabled for 1 minute to allow cooling down.
Finally, if all of the above protections fail the temperature sensing switch
•
inside the transformer will break the input current if its temperature rise is
too high. This mechanism resets automatically after cooling down.
The control of the relay is synchronized with the mains input, it switches on and
off during the zero crossing off the current to prevent induction voltages
(spikes).
If the supply voltage for the control part becomes too low (long power dips) the
output will be disabled. After restoring of the mains supply the product will start
again in the last known mode.
