CPS-EX2000 SERIES

Product Overview

CAMTEC - CPS-EX2000 SERIES 

2000W Power Supply scalable 19“ embedded 2U/3U or hardmount in all positions, PFC 0,99  

Available Outputs:   24-30V,  30-45V,  45-58V,  58-90V,  90-150Vdc  

Description   The CPS-EX power supplies provide low noise and ripple, a very quick programming, and an absolutely precise setting at high load changes. With an efficiency of 92-94% and a power factor of 0.99, the devices are highly energy efficient. Equipped with high-end capacitors of outstanding lifetime our power supplies guarantee a very long and reliable operation time. The circuit design of the CPS-EX Series allows cope playing with complex loads. The internal protection circuits protect the power supply and the connected system, even in exceptional situations. The CPS-EX series is protected from high transients by strong filters with high energy efficiency. All inputs and outputs and the interface are electrically isolated. The design specifications call for the highest standards of safety and interference suppression. The device was developed in accordance with the requirements of IEC/CSA/UL60950-1 and the EMC standards EN55022 conducted Class B, radiated Class A.

The mechanical design of the CPS-EX2000 device series is unique. It is the first power supply line in the world market, which can be flexibly adapted to any installation situation. .   The forced air cooling system with monitored and load-dependent variable fan control, allows a detached position in the system. By simple and cost-effective wall brackets the device can be integrated in any position in 90° increments. Unlike comparable power supplies Camtec comes here for the first time to let the system integrator completely free hand. The cooling concepts for supply and exhaust air can be designed to completely remove the heat dissipation from the cabinet. Complex and expensive air-conditionings for switch cabinets can be reduced to a minimum or even completely eliminate. Brackets for air channels are available as an option. In selecting the fan, as with all our power supplies, in our opinion we use with the German manufacturer EBM Papst the highest quality and most reliable devices in the world market. The installation of the power supply in a 19" subrack is guaranteed in the simplest way. Again, our engineers have decided to offer a completely open and flexible system. The optional front panels allow the power supplies the use in either a 2U or 3U subrack. In this way we can realized 9kW in 2U-rack and up to 15kW in a 3U-rack with the CPS-EX2000 models. Up there is almost no limit: With Zero-Stacking the series allows scalable DC supplies of over 100kW in a single small 19" rack. As accessories for the CPS-EX Camtec provides matched 19 "subframes. Our subracks deserve the name of a carrier, because they really are extremely stable made of stainless steel. The power supplies have nickelplated steel pins to position the power supplies in the subframes. The so married together systems withstand the toughest conditions. All mechanical connections in the power supplies or on the racks are constructed with A2 or nickel-plated screws, so that they provide maximum protection against corrosion and conductivity.

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
