72V, 110V, 150V, 220Vdc
The Camtec HPV series is a high precision switch mode power supply for an upscale demand. It is engineered
and manufactured by CAMTEC in Germany. The designed meets challenging applications like complex dcdrives,
piezo print head, test-stands, and professional machine-building. The power supply provides a low
ripple-noise, a precise load-regulation and high efficiency up to 93%. High-end long life capacitors guarantee
an extended hold-up-time and an extraordinary lifetime of the power supply. The circuit design starts complex
loads easily. The internal control circuit manages illegal operating conditions to prevent your system from
damages. The HPV series features active high input transients with suppressor diodes, X2-capacitors and
varistors. All inputs, outputs and feature connections are galvanic isolated. The design rules set value on
extended interference immunity and safety. The unit is designed in accordance to the EN60950-1 and the EMCcompatibility
to EN55022 class B norms. Our engineering design is made in accordance to the CSA/UL60950-
1 and the IEEE CB scheme rules.
DC-ok Power Good Relay
The PG Relay connection indicates over temperature,
low DC-voltage at the output and low AC supply
voltage at the input.
The power supply is galvanic isolated between the
input and the output. All features like the Power Good
Relay are connected to the DC power outputs
The HPV is featured with a thermal overload shut
down and auto recovery behaviour.
Short Circuit Protection
A continuous short circuit does not cause damage to
the power supply. The HPV delivers constant current
and 0 output voltage. It recovers automatically after
the short circuit is released.
Open Circuit Protection
The HPV series is continuously open circuit protected.
The device delivers a stable output voltage and no
current. If a load is immediately connected to the
device, the power supply stabilizes within 1ms. It does
not overshoot the output voltage
Power Up Ramp
The devices has a soft start ramp when powering up.
The device does not either overshoot the voltage nor
does the output flutter – independent if a load is
connected or not.
Current Voltage Chart, CV & CC mode
The HPV series provides a perfect current voltage
chart. It has no fold back or other abnormalities. The
output voltage can drop down to zero volts when the
power supply is overloaded. The unit delivers a stable
and constant current to the outputs.
