Fredenstein Bento10S 10-Slot 500 Series Module Carrier, Onboard Audio Routing

The Fredenstein Bento 10S is a high performance module carrier for Fredenstein Series 600 modules or API-500 compatible plug-in cards. The unit can accept a maximum of 10 modules. The Bento 10S features several important upgrades compared with third party products: Universal power supply: Mains voltages range from 90V AC to 240V AC, 50 to 60 Hz. Increased output currents: +/-16V DC +/-3A and +48V DC 0.25A, 600mA per slot which is more than double the standard calls for.

The Bento 10S power supply is also designed for extremely low noise largely due to state of the art switching regulators that operate above 200 kHz, which is typically higher in frequency than most conventional switching regulators. They also follow “green” guidelines that minimize power consumption to only what is needed.

Other features include the capability to drive very large capacitive loads. Most other switching supplies might oscillate if presented with large capacitors to charge. The Bento 10S ramps up in a controlled manner (typically 0.2 seconds). Also unlike most +/- switching regulators, both the +16V and -16V are regulated independently and provide separate over current protection.
