Predictika · Power supply selection

An AI sales agent's power supply selection, checked before it goes out

An AI sales agent recommends a 10 W AC-DC power supply from the ECE10 series for a customer's design: the model for the output voltage, the mounting style, the input supply, the continuous and peak load, the ambient temperature and the nominal current for the quote. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the manufacturer's public datasheet and returns a verdict, every reason and the figures it computed.

Scope: Selections from the ECE10 series (ECE10US03 to ECE10US48, encapsulated or open frame): output voltage, input, load with derating, peak load, ambient temperature, altitude and nominal current. See everything this validator covers

This validator models selections from the ECE10 series, not just the scenarios shown below.

  • Models — the seven output voltages 3.3, 5, 9, 12, 15, 24 and 48 V; a model that does not deliver the voltage the design needs is blocked.
  • Input — 85 to 264 VAC at 47 to 63 Hz, or 120 to 370 VDC; the load is derated for AC input between 85 and 90 V.
  • Load and ambient — the continuous load is compared with the nominal current after derating for low AC input and for ambient temperature above 50 C (to 50 percent at 70 C); the peak load must stay within the peak rating and last under 30 seconds at a duty cycle of 10 percent or less; ambient temperature from -25 to +70 C and altitude up to 3,048 m.
  • Mounting and stated current — the open frame version (suffix -P) is for OEM quantities and goes to a person for confirmation; the nominal current on the quote is compared with the datasheet figure.

Any selection from this series that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the datasheet lists none, so this validator produces no price build-up), the quantity at which open frame becomes available, other XP Power series, and approvals or EMC suitability for a specific end product.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A usable load that depends on input voltage and temperatureOnly with workarounds
The current available falls at low AC input and again above 50 C; the two derating curves multiply, so the rule has to be built as a computed value and then compared with the load.		The derated current is computed from the model, input and ambient temperature on every call and compared with the load.
An input range that depends on AC or DCOnly with care
AC and DC have separate windows and only AC has a frequency range; a rule per case is workable but easy to miss.		The input type, voltage and frequency are checked together.
A peak load with two limitsOnly with care
A peak must be under the peak rating, shorter than 30 seconds and infrequent enough; three conditions that have to be remembered together.		The peak rating, duration and duty cycle are all checked and each failure is reported.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the selection is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent recommends a 10 W AC-DC power supply from the ECE10 series for a customer's design: the model for the output voltage, the mounting style, the input supply, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the manufacturer's public datasheet and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote the ECE10US12 power supply, the encapsulated version, for a design that needs 24 V at 350 mA continuous and a peak load of 1200 mA for 20 seconds at a 5 percent duty cycle. The quote states a nominal output current of 830 mA. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The model on the quote does not deliver the required output voltage; the required output is 24 V and the model gives 12 V. The AC input of 270 V is outside the 85 to 264 VAC range of the ECE10 series. The peak load of 1,200 mA is above the 1,000 mA peak rating of this model.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a usable load that depends on input voltage and temperature, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to ECE10US24, the input voltage to 230 V, the peak load to 450 mA and the stated nominal current to 410 mA.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
