The Evaluation board is used for both the analog-control and digital-control BCM products. The focus of this document is to assist the user in evaluating the analog-control version of the BCM family. The BCM evaluation board can be configured for various enabling and fault-monitoring schemes, as well as to exercise various loading conditions depending on the application requirements. The evaluation board can be used to evaluate BCMs in either a stand-alone configuration, or as an array of modules. It is important to remember the fast response of BCMs can readily show the limitations of the source, load and associated wiring connected to the evaluation board. Care should be exercised to minimize the stray source and load impedance in order to fully exercise the BCM. Refer to the appropriate data sheet for performance and operating limits. Data sheets are available at www.vicorpower.com. Enable Options: 1. Apply input voltage greater than the BCM undervoltage lockout (Default) 2. On-board mechanical switch 3. External control using available test point Fault Monitor Options: 1. On-board LED: the VAUX pin drives a visible LED for visual feedback on the BCM status such as enabled or fault condition. UG:015 Page 1 IMPORTANT NOTICE: Hazardous voltages are present on the HV BCM Evaluation Board under power. PERSONAL CONTACT WITH LINE VOLTAGE MAY RESULT IN SEVERE INJURY, DISABILITY, OR DEATH. IMPROPER OR UNSAFE HANDLING OF THIS BOARD MAY RESULT IN SERIOUS INJURY OR DEATH. Read the precautions below entirely BEFORE using the BCM evaluation board. Do not operate the evaluation board unless appropriate bench safety precautions are in place to guarantee safety. The list below is not comprehensive and is not a substitute for common sense and good practice. nnDuring operation, the power devices and surrounding structures can be operated safely at high temperatures. nnRemove power and use caution when connecting and disconnecting test probes and interface lines to avoid inadvertent short circuits and contact with hot surfaces. nnNever use a jumper in place of the fuse. nnWhen testing electronic products always use approved safety glasses. Follow good laboratory practice and procedures. nnAvoid creating ground loops when making measurements of the isolated input or output voltage. nnCare should be taken to protect the user from accidental contact when under power. nnCare should be taken to avoid reversing polarities if connecting to the opposite (solder) side of the board. nnThe product evaluation boards described in this document are designed for general laboratory evaluation and are not suitable for installation in end user equipment. nnRefer to the specific BCM module data sheet for electrical, thermal, and mechanical product details. These boards provide a convenient way to evaluate / demonstrate the performance of the Vicor BCM products. Kelvin connections are provided for accurate voltage measurements on power nodes. Sockets are provided to permit quick installation and changing of bulk-lfi tering capacitors. The evaluation board also provides lugs for Input / output connections, test points and sockets for easy connection to standard test equipment and a high performance air-cooled heat sink assembly. Contents The evaluation board arrives with the following contents: nn1 x BCM evaluation board nn1 x Top heat sink pre-installed as well as a bottom of the ChiP heat sink when applicable nn1 x Hardware kit: nn1 x through hole aluminum-electrolytic output capacitor (C121) nn3 x Connector receptacle 8 position nn2 x Connector socket 2 position nn5 x Size 10 screws, lugs and washers UG:015 Page 2
