DC1-1D... variable frequency drives feature a voltage doubler in their internal
DC link. When there is a connected voltage of 1 AC 110 - 115 V, a motor
voltage of up to 3 AC 230 V will be output.
① Devices with a frame size of FS2 allow for DC link coupling (DC+, DC-)
and connecting brake resistors (DC+, BR).
Brake resistor DX-BR3-100 can be inserted underneath the heat sink into the
enclosure and electronically protected against overloads (P-34 = 1).
￫
DC1-1D... variable frequency drives do not feature an internal
radio interference suppression filter. An external radio
interference suppression filter is required for operation as per
EN 61800-3, ￫ Section 6.8, "Radio interference suppression
filter", page 169.
