Dycon brings switched mode technology to access control
Mountain Ash, Glamorgan
The switched output is designed for highly inductive loads such as access control door strikes and locks and is protected to control high voltage back-EMF spikes. This makes the D244X Series an ideal power supply for access control applications with door strikes and systems requiring automatic door release - the D244X Series power supply can be remotely controlled to switch off power and allow automatic door release or closure when required.
In common with all Dycon switched mode power supplies, the D244X Series uses considerably less power than conventional linear units, providing a highly efficient power conversion, better than 85% at full rated output. According to Dycon using the D244x Series of switched mode 24 volt power supplies is reasonably priced and they are more energy-efficient than conventional linear power supplies as well as having lower running costs.
The power supplies are available in 1.0, 3.0 and 5.0 Amp versions, and they are quick and easy for status monitoring with LED display to show monitored faults such as PSU fault, battery fault and AC power status.
The On/Off power switching control input will allow the user to switch the PSU off and permit opening/closure of automatic doors when needed, and the status LED display indicates normal/standby operation and On/Off switching status to check quickly and easily the status of the PSU. Over-voltage output protection will switch off the power supply if it reaches too high a voltage (around 30 volts). There is a jumper to select inverted or normal power switching operation and inductive and capacitive load switching surge protection and snubbing, and an intelligent electronic fuse output protection with automatic reset are safety features which stop the PSU from blowing up when too much current is applied for example.
Constant current battery charging allows faster charging, which means time and cost savings in the long term. The power supply unit is available in PCB format or housed in a metal enclosure (2 different sizes available) to suit most applications.
