Dasm Application Considerations - Advanced Energy Thyro-PX Series User Manual

®
Advanced Energy
For systems in which there are multiple power controllers, individual power
controllers are synchronized so that a regular mains load is achieved. This avoids
random load peaks caused by multiple power controllers switching on at the same
time. The upstream transformer and/or the upstream feed point can be designed for a
lower load, which results in savings in investment and operating costs, and much
smaller system perturbations.
dASM can be applied whenever multiple power controllers operate together on a
common grid supply in the TAKT mode. Other features include:
• Grid load optimization for up to 32 power controllers in the TAKT mode
• Grid load optimization on the basis of power consumption of the connected
loads
• Dynamic grid load optimization, including the observance of setpoint or of the
load alterations
• Digital operation and communication
• Grid load optimization of the dASM group within up to 5 seconds
• Suitable for 1-phase or 3-phase applications
• Simple dASM wiring with shielded RJ-45 patch cables (Ethernet CAT 5 8-pole)
with a cable length between two power controllers of up to 100 m (328')
depending on surrounding conditions
• Simple parameterization of monitoring features in the master unit (including
configurable total power limit and number of devices)
• Monitoring the grid load (power limit)

dASM Application Considerations

When designing and installing, ensure that the:
• Electric load is evenly distributed onto the 3-phase system
• Parameterization and initiation of the individual power controller devices are in
the TAKT mode with the same TAKT cycle period (To)
• Power wiring is correct for the phases
• 1-phase and 3-phase loads are in separate dASM groups
• Power controllers and loads of a dASM group are connected to the same grid in
phase
• Shielded RJ-45 patch cables connect the dASM In and dASM Out connectors
of each unit
◦ Remove a section of the outer cable jacket to expose the shield.
◦ Place the exposed shield section of the cable under the shield clamp.
◦ Plug the RJ-45 connector into the unit.
