Specifications - CPX200D & CPX200DP
OUTPUT SPECIFICATIONS (each output)
Voltage/Current/Power Levels
Voltage Range: 0V to 60V.
Current Range: 0A to 10A.
Note: Actual maxima for voltage and current are typically 1% greater than the figures given above.
Power Range: Up to 180W subject to power envelope.
POWER ENVELOPE
The maximum current at any voltage settings is limited by the power envelope which is set to
give 3A at 60V rising to 10A at 16V under all ac supply conditions (both outputs loaded). At
lower output voltages the power is restricted by the 10 amps current maximum.
See PowerFlex power envelope graph on page four.
Output Setting & Control
Voltage Setting: By coarse and fine controls.
Current Setting: By single logarithmic control.
Output Mode: Constant voltage or constant current with automatic cross-over.
CC indicator lit in constant current mode.
Output Switch: Electronic, non isolating. Preset voltage and current limit displayed
when Output is off. Output rise time no load <10ms.
View Settings: With the output On, the meters show actual voltage and current.
The preset levels can be viewed and adjusted at any time by pressing
the View Settings button.
Status Indication: LED indication of Output On, V/I Limits, CV, CI, Power Limit, Remote,
LAN status. Message on meter display for trip condition.
S-Lock
(Settings Lock) Voltage and current settings can be locked by a single button press.
Lock accuracy is equal to the meter accuracy (see Meter Specifications).
Output Performance
Ripple & Noise: Typically <1mV rms, <15mV pk-pk, (3mV rms max.) in CV mode.
Load Regulation: Voltage - <0·01% of maximum output for any load change within
the PowerFlex envelope (remote sense connected).
Current - <0·05% of maximum output for any load change within
the PowerFlex envelope.
Line Regulation: Voltage - <0·01% of maximum output for a 10% line change.
Current - <0·01% of maximum output for a 10% line change.
Transient Response: <250µs to within 50mV of setting for a 5% to 95% load change.
Temp. Coefficient: Typically <100ppm/°C
Output Protection
Output Protection: Forward protection by Over-voltage Protection (OVP) trip.
Reverse protection by diode clamp for currents to 3A.
OVP Setting/Range: Via screwdriver adjustable preset on front panel. Range 1V to 66V
Over-temperature: Output trips off for over-temperature.
Safety Interlocks: Operations that could cause an unexpected change in voltage or
current settings are interlocked with the output switch.
Output Connections
Output Terminals: Universal 4mm safety binding posts on 19mm (0·75”) spacing at front.
Screw terminals at rear (CPX200DP only).
Terminals can accept fixed shroud 4mm plugs, standard 4mm plugs, fork terminals and bare wires.
Remote Sense
Sense Selection: Voltage sensing is selected as Local or Remote by front panel switch.
Sense Terminals: Sprung loaded screw-less terminals at front.
Screw terminals at rear (CPX200DP only).
METER SPECIFICATIONS (each output)
Display Type: Dual 4-digit meters, 10mm (0·39”) LED.
Voltage Meter
Resolution/ Accuracy: 10mV / ± 0·1% of reading ± 2 digits
Current Meter
Resolution/ Accuracy: 10mA / ± 0·3% of reading ± 20mA
VOLTAGE TRACKING
Independent Mode
In the normal mode of operation, each output is fully independent and isolated. Operation is
equivalent to two single output power supplies.
Voltage Tracking Mode
The two outputs remain isolated, but the Slave voltage controls are disabled and the Slave
voltage is set equal to the Master voltage. This can be used to generate tracking bipolar volt-
ages, or tracking unipolar voltages relative to different grounds.
When voltages greater than 60V are required, the outputs can be wired in series to generate
0 to 120V with the voltage controlled from the Master.
When currents greater than 10A are required, the outputs can be wired in parallel to create
the equivalent of a 20A power supply with the voltage controlled from the Master.
Track Accuracy: Slave voltage = ± (0·1% of Master voltage setting + 10mV)
BOTH ON / BOTH OFF
Each output has an independent DC On/Off control, however, an additional control button is
provided which turn both outputs on or off simultaneously.
DIGITAL BUS INTERFACES (CPX200DP only)
The CPX200DP offers full remote control and read-back using RS-232, USB, GPIB or LAN
(compliant with LXI class C). All interfaces are at ground potential and opto-isolated from the
output terminals. Note: Remote/Local Sense, is manually selectable only.
RS-232
Standard 9-pin D connector. Baud rate 9,600.
USB
USB 2.0 connection (backwards compatible with USB 1.x). Operates as a virtual COM port.
GPIB (IEEE-488)
The interface conforms with IEEE-488.1 and IEEE-488.2.
Ethernet (LAN)
Standard 10/100 base-T hardware connection. ICMP and TCP/IP Protocol for connection to
Local Area Network or direct connection to a single PC.
LXI Compliance
LAN interface is compliant with LXI Core 11 v1.4. (LXI is the abbreviation for Lan eXtensions
for Instrumentation). For more information visit: www.aimtti.com/go/lxi
