Load issues for Fire Alarms & Gate Access/Card Access
120HWCP20CBPLC
 This 120HWCP20CBPLC is very special. This unit is designed to deal with load issues. Example:
Backup Generators are not the problem while in use, however when the electrical power goes off, then every load in the building also goes off. HVAC, pumps motors, drives, elevator motors, linear power supplies and the list is long. When the power comes back on, normally they all come on at the same time which causes a huge voltage drop and the current is over the top (in over load). Many low current devices such as switch mode power supplies are affected by this load current. When the voltage drops and the current rises, the switch mode power supply does one of two things. Either the solder on the board melts and short it out, or there is a thermal run-away on the thermal fusing that blow open. Many times, are not replaceable. You would think that surge suppression would stop this issue, but that is not how they are designed. Surge suppression is designed to deal with over voltage, no matter where the current is. Surge suppression does not see anything if the voltage goes low. In series surge suppression thermal fuses would blow open, and of course our LS-E120HWCP20CB is resettable. This device also has a resettable fuse as well. This device also has surge suppression built into it as well. So the difference is the tiny computer inside this unit monitors the power, and if the voltage drops and the current is way high, it shuts off the power for three minutes. If the power goes off, it stays off when the power comes back on for three minutes as well. This way the load factor is no longer an issue, because the power should stabilize after three minutes. The cost of this unit is $600.00 retail.  
The only other thing that might come close to being just as effective is a true on-line double conversion UPS and generally a hardwired version is over $2000.00. So, this device either retail or wholesale is the cheapest option to deal with this issue.
