Raven Installation Guide Introduction
MAN-RAVIG (Ver. 1.1)
2-2
2.2 Product Description
The Raven is a series of miniature ExtrIQ current mode servo amplifiers for brushless
motors with sinusoidal commutation. Although highly compact, the Raven can withstand
extended environmental conditions and support up to 35 Amps. This high power density
servo amplifier can deliver up to 4800 W of peak power or 2400 W of continuous power
in a miniature package. The servo amplifier offers significant operating features
including excellent output linearity and zero dead band performance.
The Raven incorporates custom mixed analog/digital ICs and a hybrid power stage. The
basic configuration is a current mode amplifier targeting the OEM market. As such, no
trimmers are used in the basic version. In addition to its compliance with relevant MIL
standards, the Raven amplifier also meets UL508c and the relevant CE regulations.
The Raven power stage is implemented on a single ceramic substrate. This design enables
very high thermal conductivity, high current carrying capacity, improved EMC and good
mechanical strength. The control section is implemented by dedicated custom ICs that
contribute to enhanced performance.
