PCB Power Supplies
A750x
PCB High Voltage Power Supply Family
Delivering the excellence of CAEN High Voltage
Technology in the palm of your hand!
Features
• Single channel PCB mount High Voltage Power
Supply
• High efficiency and low power consumption
• Four models available:
- A7501 (2100 V / 100 μA)
- A7504 (4000 V / 100 μA)
- A7505 (1600 V / 500 μA)
- A7508 (800 V / 50 μA)
• Positive or negative polarity
• Analog voltage and current Set and Monitor levels
• Very low ripple and noise
• Excellent stability
• Compact package 54x29x17 mm3 (WxLxH)
• High operating temperature range:
- A7501: -40 °C ÷ +70 °C
- A7504: -10 °C ÷ +50 °C
- A7505: -55 °C ÷ +80 °C
- A7508: -40 °C ÷ +70 °C
The A750x is a new line of compact, high
efficiency, low noise single channel High Voltage
DC/DC converters in a PCB mount form factor.
Each device can supply a High Voltage output
according to an external reference voltage level
(Vset) provided by the user.
Maximum current setting (Iset), voltage monitor
(Vmon) and current monitor (Imon) are also
available. These features make the A750x family
suitable for integration in user designed systems
or embedded applications.
Power Supply / PCB Power Supplies
Four models are currently available, A7501, A7504, A7505,
A7508, supplying up to 2100 V/100 μA, 4000 V/100 μA, 1600
V/500 μA and 800 V/50 μA respectively. Each A750x can be
provided with either positive or negative polarity. Other models
can be designed on request.
Thanks to their excellent stability and special design, A750x
Power Supplies are engineered to work in harsh environment and
under severe temperature variations.
Safety features include:
• Overcurrent detection: if the channel attempts to draw a current
larger than Iset, the output voltage is varied to keep the current
below Iset limit. The channel behaves like a current generator
• Status Overcurrent Bit: 0 ÷ 5 V (low = OVC)
• Status On/Off Bit: 0 ÷ 5 V (low = OFF)
• Protected against short circuits, sparks and humidity
