Features
Idling behavior
The CPS-EX Series is permanently open-circuit proof. When an output
voltage is preset it comes stable. If a load is switched suddenly, the unit
stabilized within <1ms. An overshoot of the output voltage is irrelevant.
Start behavior
The power supply has a start delay of 1s to stabilize all measuring circuits
for the interface messages accurately. The power supply starts with a
ramp (soft start) of 100ms. The output voltage does not overshoot -
regardless of whether a load is connected or not.
Galvanic isolation and insulation
The switching power supply is galvanically isolated between the input and
the output. All major digital inputs and outputs of the interface are
electrically isolated.
V programming (Ureg)
The output voltage of the CPS-EX power supply can be adjusted by a
control signal. The setting is linear to the input signal. The power supply
operates data stable even at all output voltages.
C programming (Ireg)
The output current of the CPS-EX power supply can be adjusted by a
control signal. The setting is linear to the input signal. The power supply
operates data stable even at all output currents.
V Monitor (Umon)
The power supply provides real-time monitoring of the output voltage. It is
the exact and real value at the output terminals. If the sense line is used,
the real value is measured directly at the load. The latency signal preset to
the measured value is negligible since the control circuit is constructed
completely analogously.
C Monitor (Imon)
The power supply provides real-time monitoring of the output current. It is
the exact and real value at the output terminals. The latency signal preset
to the measured value is negligible since the control circuit is constructed
completely analogously.
Constant Voltage or Constant Current Mode (CV/CC)
The device can be operated as a DC voltage source or a constant current
source. The operating mode is signaled on the interface.
Auxiliary Voltage (AUX)
The devices feature a 12V / 500mA auxiliary voltage to operate external
peripheral.
Potentiometer Internal Control (Uadj/Iadj)
If the power supply shall only set with the built-in internal potentiometers,
the use of the internal reference voltage is possible. The power supply
requires no external signals and can operate completely autonomously.
Potentiometer External Control (Uadj/Iadj)
If the power supply shall only set with external potentiometers, the use of
the internal reference voltage is possible. The power supply requires no
external signals and can operate completely autonomously.
Sense Mode
The power supply has a sense mode to compensate for voltage drops of
2V per load line.
Fuse Mode
The unit can be operated in fuse mode. In the fuse mode, the unit is turned
off and locked when it was more than 5 seconds in constant current mode
to protect a connected defect load. The lock can be controlled remotely or
repeal by disconnection from the mains again.
Continuous Mode
The unit can be operated in continuous mode. In the continuous mode, the
power supply provides constant current mode in a continuous flow and no
ticker-operation.
Master-Slave Mode (Ureg-OUT/Ireg-OUT)
The master-slave mode can be defined in the parallel operation. One device can
be set as the master, the other involved network units act as a slave and the
setting signals follow current / voltage, which are commanded by the Master. This
ensures that all devices are operated synchronously.
Current Share Bus (CS)
In parallel operation, the involved network components communicate with each
other and share the total power evenly to each other.
Remote Shutdown (SD)
All CPS-EX devices have a remote shutdown (open collector or switching
contacts).
Inhibit Mode (Interlock)
The inhibit circuit reliably prevents unintentional starting of the power supply. The
control loop is internally locked. Since this blocking is done progressively it is
active even when the control signal, is missing due to a cable break or temporarily
suspend. A premature restart of the power supply is prevented.
The inhibit input can be connected to a relay or switch. If the contact is interrupted,
the power supply is switched off. If the contact is closed again, the power supply
restarts.
DC and AC Fail
By DC-fail the power supply reports that the power output is disabled.
By AC-fail the power supply reports an AC undervoltage. Both signals have
separate outputs. Each of them can be selected between NO and NC.
Over Voltage Protection (OVP)
On the interface is a message signal. Until the abolition of the fault the device
switches off.
Over Current Protection (OCP)
On the interface is a message signal. Until the abolition of the fault the device
switches off.
Temperature Control (TEMP)
The operating temperature of the power supply can be monitored via a signal
applied to the interface output.
Temperature Alarm (TA)
If the device is in the critical range, a warning signal is applied to the interface.
Over Temperature Thermal Shutdown (OT)
The device has a thermal monitoring: shutdown with automatic restart. The OT
signal is applied to the interface.
Fan Failure Monitoring (FF)
If it comes to a fan failure or blocking, a signal is applied to the interface. The
speed signal of the fan is monitored. Thus, even a creeping fault is detected at an
early stage and there is a warning long sold separately in front of a fan failure.
3D Heat Dissipation
Our aligned and controlled heat dissipation design opens possibilities that are
formerly being reserved to custom design power supplies: Steplessly hard mount
of the CPS-EX2000/3000 power supply modules in a 3D-room.
In practice that means that one can mount the modules into every angle
imaginable. Our 3D heat dissipation (3D-HD) ensures optimal cooling in each
mounting position you may consider.
Design-to-Service:
Most recorded failures in the field concern the signal interface of a power supply.
Camtec offers new concept of design-to-service that allows the customer easily to
exchange the interface himself in the field. The analogue and digital interfaces
apply plug & play self calibrating and can be used independent from the model
CPS-i/EX/EP 2000 & 3000 Thus, system down cost is being reduced and only a
small amount of spare parts need to be stocked by the customer.
