Frequently Asked Questions - QPX600DP Aim TTi

What is the maximum power per output on the QPX600DP?

The maximum power per output is 600W, but only within the PowerFlex envelope defined by the voltage and current limits. Outside this envelope the output becomes unregulated (UNREG mode).

How can I synchronize both outputs?

Use the BOTH ON and BOTH OFF keys to switch both outputs synchronously within ±10 μs. Alternatively, use LINK modes for voltage or current tracking.

What remote control interfaces are available?

The QPX600DP model offers RS232, USB, LAN (Ethernet, LXI Core 2011), and GPIB (IEEE488.1/488.2) interfaces for full digital remote control.

How do I set over-voltage protection (OVP)?

OVP range is 2V to 90V with 0.1V resolution and accuracy 0.2% ± 0.2V. Response time is typically 100 μs. It can be set via the keyboard or remote commands.

Can I monitor output voltage and current remotely via analog signals?

Yes, analog monitor outputs provide 0-10V or 0-5V signals representing actual voltage and current. Accuracy is 0.3% ± 4mV for voltage and 0.5% ± 40mA for current.

What is the purpose of LOGIC IN and LOGIC OUT?

LOGIC IN is an opto-isolated input that can enable or disable the output. LOGIC OUT is an open-collector output that indicates output status, current limit, power limit, or fault trips.

How do I connect outputs in series or parallel?

Use the LINK menu to set tracking modes. For series connection, set V2 to track V1 (1:1) and display total V1+V2. For parallel, set V2 and I2 to track V1 and I1 and display total I1+I2.

What is the maximum current for the output terminals?

Rear panel safety terminals accept 6mm wire, 6mm plugs or 8mm spades at 50A max, or 4mm plugs at 30A max.

Does the QPX600DP have memory for storing setups?

Yes, up to 10 instrument setups can be saved and recalled via the keyboard or remote interfaces.

What is the typical transient response time?

For a 5% to 95% load change, the output recovers to within 100mV of set value in less than 2ms.

LOGIC CONTROL INPUT and OUTPUT (Each Output)

LOGIC IN is a rear-panel opto-isolated input with an 820Ω resistor in series that is activated at an input voltage greater than approximately 3.3V. The maximum voltage that can be applied without damaging the unit is 20V and the input should not be taken negative by more than 3V. User can set LOGIC IN (via the keyboard) to enable the output, disable the output, or be ignored when it is activated.

LOGIC OUT is an isolated rear-panel open-collector output that will sink up to 2mA when activated ('switch closure'); the maximum voltage that can be applied to LOGIC OUT is 30VDC. User can set LOGIC OUT to be 'closed' or 'open' for output enabled or disabled, current limit (CC mode), power limit (UNREG mode), or for any fault trip.

ANALOG REMOTE CONTROL and MONITORING (Each Output)

Quasi-analogue inputs and outputs to set voltage and current limit and to monitor actual output voltage and current. The control inputs are read four times per second by the A-D converter and the output is set according to the selected input scaling; similarly the monitor outputs are updated four times per second with values representing the actual output voltage and current. These signals each have a range of 0 to 10V or 0 to 5V with respect to the shared COM return signal; the set range applies to all inputs and outputs.

KEYBOARD & ROTARY CONTROL

All functions, including the selection and set-up of the remote control interfaces, can be set from the keyboard. The rotary Jog control can be used to adjust output voltage and current settings in a quasi-analogue mode. The output to be controlled is first selected with the appropriate Control key.
