350W controllable converter, DC-DC, isolated, regular or with options and customizations

Description

Control setting for this controllable converter: 0 to 10V → 0 to 32V / 12.5A / 350W
Mini module, half brick type.
This DC-DC controllable converter comes with standard or optional or customized features.
Insensitive to moisture, dust, shock and vibrations, with IP67 molding.

Supply voltage

• Nominal voltage: 24V
• Range: 18 to 36V
• No-load consumption: 45mA (or 25mA when off)

Control setting (the “zero” of the control is shared with the “zero” of the output)

• Standard: 0 to 10V → 0 to 32V
• Optional:
  • 0 to 20mA → 0 to 32V
  • 0 to 20kΩ ±10% → 0 to 32V (external or built-in potentiometer)
• Customized: the voltage can vary from zero to any maximum between 2Vdc and 200Vdc (you choose) → 0 to 32V.

Linear output voltage (input / output isolation: 1500V)

• Standard: 0 to 10V → 0 to 32V
• Possible options:
  • lower maximum; example: 0 to 10V → 0 to 19V
  • shifted minimum; example: 0 to 10V → 8V to 32V
  • shifted minimum and maximum; ex.: 0 to 10V → 20V to 28V

Output current

• Standard: 0 to 12.5A  /  350W, depending on load; in case of abnormal overload > 13A, the output voltage starts hiccupping
• Options “constant current generator”
  • in-built setting (axis Ø 3mm, 10 rounds) or external setting
  • controllable by 0 to 10V → 0 to 12.5A max / 350W max

Response time

• Rise time from 0 to 32V / 10A: ≤ 12ms
• Down time: depends on the load

Other characteristics

• Line and load regulation: 10^-3 of Vout
• Control accuracy: better than 0.5%
• Efficiency at full load: ≤ 91%
• Efficiency at half-load: ≤ 89%

Thermal characteristics

• Storage temperature: – 55°C to +125°C
• Operating temperature of the case: – 40°C to +90°C
• Thermal resistance of standard case 2A: 6°C / W
• Temperature drift: 2.10^-4 of Vout / °C

Cases

• Standard cases 2A and 3A
• Optional or special cases:
  • for PCB (80x 63 x 16 mm)
  • with built-in mini fan
  • with overmolded wires at the outputs

Standards and particularities

• CE / UL 60950-1 / RoHS marking
• MTBF > 10⁶ hours at 30°C
