Technical information
Cooling capacity and efficiency
Greater power density, increasing miniaturisation and extreme electronic
component density are posing increased demands on the cooling capacity
and efficiency of fans. The intelligent and space-saving integration of the
fan in the device configuration is therefore of major importance:
• Tailor-made cooling adapted to the situation as and when required.
• Programmable cooling by defining speed profiles.
• Transparency of function thanks to complete, interactive monitoring in
all operating conditions.
Standard fans in electronics cooling have proven themselves millions of
times.
With a constant speed and a correspondingly high noise level, they continuously provide the air flow needed for extreme cases. These extreme
situations, however, occur extremely rarely, if at all, during the operating
period. An intelligent fan is needed, which adapts automatically to the
currently required level of cooling.
2016-01
ebm-papst provides intelligent cooling concepts which are optimally
adapted to requirements. For example:
166
1. Speed adjustment via temperature sensor
ebm-papst answers with a complete range of DC fans with temperaturecontrolled speed adjustment via a temperature sensor, available in a
variety of standard dimensions.
Installation is very simple. The control electronics receive thermal
information for the speed adjustment continuously and without losses,
either externally via a freely designed and positionable strand, or
internally directly in the fan hub in the air flow. A range of temperature
sensors can be found on page 178.
2. DC fans with separate control input
Open or closed-loop speed control is also possible with DC fans that have
a separate control input. A variation in speed can thus be implemented via
a control voltage or a pulse-width modulated signal. These possibilities
are used primarily in devices that have appropriate standard interfaces
and thus require a load-dependent variation of the fans.

7. Protection against environmental influences
Some applications place particular demands on the fans resistance to
ambient influences, such as dust, moisture, water and salt. ebm-papst
offer solutions for adapting fans to these ambient conditions.

5. Turbo drives
Fans with three-phase EC drives and microprocessor-controlled motor
electronics. These three-phase motors whose torque is virtually nonreliant on the rotor position are used for extremely high running smoothness. The speed of these fans can be controlled over a very wide range
with PWM, analog voltage or temperature. Optionally, the fans can be
supplied with reversible direction of rotation and active brake operation.
The successful concept of Vario-Pro is: Tailor-made software instead of
fixed hardware, because programmed software modules for motor control
and application intelligence are responsible for the work that analog components were responsible for in the past. This central control unit of the
Vario-Pro comprises a microcontroller and an EEPROM, on which all characteristics are stored.

4. Alarm signal
For applications which require monitored fan operation with alarm
signal, ebm-papst has numerous alarm signal versions, either a static,
pre-processed or interface-compatible high or low continuous signal
depending on the type of fan.
6. Vario-Pro fans
This high-end fan concept by ebmpapst with programmed intelligence
and customer-specific integrated functions makes your electronics
cooling even more versatile and competitive. Vario-Pro ensures a fresh
economic breeze for all demanding cooling tasks – e.g. where greater
reliability, more flexibility and intelligent function features such as alarm
function, speed control etc. are required.
2016-01
3. Speed signal
DC fans with speed signal.
The integrated „electronic tachometer“ continuously provides an actual
speed signal for external evaluation. The user is informed at all times of
the current fan speed via an extremely simple signal evaluation on the
customer side. The speed signal is via a separate lead.

– Customer can operate input either with PWM signal, analog voltage, external temperature
control module or resistor.
– The control signal-speed characteristics of the fan differ from the standard curve of the
A and P inputs (see p. 179).
– To set up maximum speed, the control wire must be connected to UB.
– The control input is usually combined with an open collector tachometer
(Type /2, see page 168).

Information
Protected fans
against environmental influences
DC centrifugal fans
DC axial fans
– Capable to fulfill special requirements for a broad range of applications
– Resistant to environmental influences, such as dust, splash water, humidity, spray water and
salt fog
– Highly competent solutions for adapting fans to environmental conditions
DC fans - specials
Degree of protection: IP 54 / IP 68
In the degree of protection IP 54, the motor and circuit boards are coated
and therefore protected against spray water and moisture.
The degree of protection IP 68 is important for ebm-papst products, as it
ensures a high degree of protection for the encapsulated motor and
electronic against foreign bodies and water, whilst protecting the user
against potential hazards upon contact. Degree of protections higher than
IP 68 are possible upon request.
Salt fog protection
Salt fog is extremely demanding on the resistance of the product.
ebm-papst makes use of technologies that protect fans and blowers
from salt fog reliably and durably.
Stainless steel bearings
Special bearings made of stainless steel provide additional protection.
ACmaxx / EC fans
Moisture protection
Coated motor and printed circuit board protects against humidity and
condensation.
