The B&K Precision Model TR-110 ISOPACK manual provides instructions for setting up and operating the isolation transformer, including selecting output voltage and connecting equipment safely. It also covers troubleshooting steps, such as checking the fuse if there is no output, and emphasizes the importance of not exceeding the power rating to prevent overload.
Manual Overview
The B&K Precision Model TR-110 ISOPACK serves as a direct/isolation transformer, crucial for safely servicing “hot chassis” AC-powered equipment. It provides isolated AC output in nine voltage steps from 90 to 140 volts, useful for identifying voltage-sensitive issues in various electronic devices. The ISOPACK features dual outlets for both isolated and direct outputs, with a continuous power rating of 350 VA for isolated outlets and 500 VA for direct outlets. Troubleshooting involves checking the 3A slow-blow fuse if the pilot lamp fails to light or there is no output from the isolated outlets. Calibration involves using the voltage select switches to adjust output voltage, with a multimeter recommended for precise measurement. The unit’s design ensures minimal voltage change under load and maintains a low leakage current. For maintenance, ensure the load does not exceed specified limits and replace fuses as necessary. The manual emphasizes the importance of grounding the chassis of the equipment being tested to prevent electrical hazards.
Quick Issues Covered
- Diagnose power-up failures by checking the 3A fuse.
- Use voltage select switches for calibration/adjustments.
- Trace circuits using the ISOPACK schematic diagram.

Operation
The B&K Precision Model TR-110 ISOPACK Direct/Isolation Transformer is used for servicing “hot chassis” AC powered equipment. It provides safety by allowing the chassis to be grounded and operates as a variable voltage source with AC output in nine steps from 90 to 140 volts. The ISOPACK has dual outlets for isolated and direct outputs, with an on-off switch and pilot lamp for the isolated output. When using the ISOPACK as an isolation transformer, connect it to a 120 volt, 60Hz outlet with the power switch off, connect the equipment to the isolated outlets, select the desired voltage, and then turn the power switch on. Auxiliary equipment can be connected to the direct outlets. The total load on the isolated outlets should not exceed 350VA continuous, and the direct outlets should not exceed 500VA. When using it as a variable voltage transformer, the voltage is selected using two 3-position switches in a matrix arrangement, providing nine possible voltage outputs. The output voltage can be varied by changing the switch positions, and a precision multimeter can be used to measure the specific voltage. A 3A fuse protects the unit from overload on the isolated outlets.

Safety & Warnings
The manual provides the following safety warnings and precautions:
1. An isolation transformer is essential for servicing any “hot chassis” (transformerless) AC powered equipment to prevent dangerous electrical shock hazards and potential damage to AC powered test equipment.
2. The ISOPACK should not be used in a confined area to avoid heat build-up.
3. The total load on the ISOLATED outlets should not exceed 350VA continuous, and a load up to 500VA may be powered for a maximum of 5 minutes if followed by an off period of 5 minutes or longer for cooling.
4. The total load of the DIRECT outlets should not exceed 500VA, continuous or intermittent.
5. Both the DIRECT and ISOLATED outputs can be operated simultaneously at up to full rated load capacity.
6. A 3A fuse protects the unit from excessive overload on the ISOLATED outlets. If the pilot lamp does not light and there is no output, the fuse should be checked and replaced only with a 3A, slow-blow type 3AG fuse.
7. If there is no output from either the ISOLATED or DIRECT outlets, check the fuse or circuit breaker panel of the building for the outlet being used to power the ISOPACK and correct any overload condition.
