Speed control
Temperature-dependent speed control for Rittal
fan-and-filter units and air/air heat exchangers
with a rated operating voltage of 230 V AC, for
noise reduction and to save energy in part-load
operation.
Technical specifications:
● For mounting on a 35 mm support rail
DIN EN 50 022
● Dimensions (W x H x D):
94 x 57 x 180 mm
● Rated operating voltage:
230 V (AC)/115 V (AC)
● Setting range: +20°C to +55°C
● Phase cross-over with microcontroller
● Maximum fan output 250 W or 1.2 A
at 230 V (AC)
● Maximum fan output 100 W or 1.2 A
at 115 V (AC)
Mounting adaptor
for speed control
The mounting adaptor enables direct attachment
of the speed control SK 3120.000/.115 to the vertical
frame sections of network enclosures.
Material:
Sheet steel, zinc-plated, passivated.
Interface card
for TopTherm cooling units with
Comfort controller
The interface card is an extension for TopTherm
cooling units with Comfort controller. It is possible,
e.g. to monitor a master/slave combination of
up to 10 cooling units. Control is achieved via
standardised interfaces: RS 232 (DB9) or RS 485,
one PLC interface (DB9). RS 422 (RJ 45 jack) is
the connection to the Rittal CMC-TC. Remote
monitoring via TCP-IP, graphical interfaces. Connection
of additional sensors for access control,
monitoring is also possible. The extension card is
built into a 1 U plastic housing. A voltage supply
of 24 V DC is needed. This may be supplied from
the CMC-TC via a wide-range power pack
DK 7320.425 (100 to 240 V AC, 50/60 Hz) or
externally via a Kycon connector.
SK bus system
The SK bus system facilitates communications
between several enclosure cooling units, Rittal
TopTherm .500/.510/.540, production date 05/02
or later, via a master/slave construction such as
that required e.g. in complex bayed enclosure
systems for optimum operating conditions.
Technical specifications:
The master/slave construction facilitates common
activation and deactivation via door limit switches,
parallel activation and deactivation via a temperature
setpoint, and common collective fault signals
and temperature logging, thereby eliminating the
need for intricate wiring.
