Features
Idling behavior
The CPS-EP 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.
Voltage set (Uadj)
The output voltage of the CPS-EP power supply can be adjusted by a
potentiometer located at the rear of the unit. The current limit is fix. The
power supply operates data stable even at all output voltages.
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.
Potentiometer Internal Control (Uadj)
The power supply will be set with an internal potentiometer. It is located at
the rear of the unit.
Sense Mode
The power supply has a sense mode to compensate for voltage drops of
2V per load line.
Continuous Mode
The unit operates in continuous mode. In the continuous mode, the power
supply provides constant current mode in a continuous flow and no ticker-
operation.
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-EP 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)
Until the abolition of the fault the device switches off.
Over Current Protection (OCP)
The power supply provides continous current when it is overloaded. The voltage
goes down to zero voltage.
Temperature Thermal Shutdown (OT)
The device has a thermal monitoring. When the temperature of the power supply
is higher than the over temperature protection threshold, the unit shuts down and
automatically restarts. An alarm 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-HD (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-EP2000/3000 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.
