TTi (Thurlby Thandar Instruments) has introduced a new version of its best-selling CPX200 laboratory power-supply unit incorporating additional features and enhanced performance The CPX200 is based on a design concept known as PowerFlex, which offers a constant-power capability allowing higher output current at lower output voltages

Electronic loads offer high current capability
The Dynaload RBL Series of single-channel electronic loads offer an exceptionally high current rating of 1000A, and are ideal for the testing of large batteries and other DC power equipment.
Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
While conventional bench supplies have a fixed current limit giving a power capability that reduces directly with the output voltage, the design of the CPX200 enables higher currents to be generated at lower voltages within an overall power limit envelope.
Each output can provide 35 V at a maximum current of 5 A.
As the voltage setting is reduced, the output current capability increases up to a maximum of 10 A.
This is achieved by using the latest switch-mode technology.
Advanced techniques are used to achieve noise and RFI figures comparable with those of good linear units.
As a result, the CPX200 can be used with confidence in sensitive environments.
The CPX200 is a dual-output power-supply unit with two completely independent and isolated outputs, each with a 175 W capability.
The outputs operate in constant-voltage or constant-current mode with automatic crossover and mode indication.
Each output has its own on/off switch.
If required, the outputs can be wired in series or parallel to achieve voltages of up to 70 V or currents of up to 20 A.
The unit offers a choice of remote or local sensing, selected via a front-panel slide switch.
Remote sensing is essential for users of higher-current power supplies who need to ensure good regulation at the load independent of connection leads.
The new power-supply unit is designed and manufactured to meet the latest safety and EMC standards.
Comprehensive protection includes an adjustable overvoltage trip for each output.
This can be accurately set anywhere in the range 3.5 V to 38.5 V.
The CPX200 is housed in a compact and robust steel case which is half-rack width and takes up very little bench space.
It is lightweight to transport and generates much less heat than a conventional unit of similar power rating.
The design is fanless, which helps to reduce noise within a laboratory.
The CPX200 costs ?649 (plus VAT) in the UK.
