Odoo 17 CRM allows us to track why we lose sales opportunities with "Lost Reasons." This helps analyze our sales process and identify areas for improvement. Here's how to configure lost reasons in Odoo 17 CRM
How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
10. Why Auxiliary Supply (1/2)
The PWM control loop uses 10V/5mA for power.
If the power supply is the input bus (rectified line
voltage) and VDD is ~10V then the PWM loop
will draw (160V-10V)*5mA=7.5W
The secondary output can’t be used because
galvanic isolation is required
Auxiliary supply allows low power consumption
and galvanic isolation.
Cost is low.
10
11. Why Auxiliary Supply (1/2)
Transformer action will also apply between the
secondary voltage and the auxiliary voltage.
Fault tolerence when reference/opto fails: No
overvoltage seen at output.
Short circuit behavior: with aux winding the max
output power is limited, no need to oversize
secondary side components.
