Product Description
200FB4031 is a DC drive in the FlexPak 3000 series, manufactured by Reliance Electric. It is a Regenerative DC driver that includes an inverting fault breaker. The drive is designed to operate at 200 HP with an input voltage of 460 VAC. The drive is U/L and U/L-C certified. The drive is intended to be used with the FlexPak 3000 Series Regulator Software V3.
In some cases, a transformer may be used with the drive. In this situation, a power disconnecting device should also be attached. If the power disconnecting device is a circuit breaker, it is ideal to use a breaker that is 10 to 12 times the full load current of the drive. An isolated transformer, line reactor, or other method of introducing impedance may also be required if KVA for the drive is exceeded. Isolation transformers also have added benefits of reducing disturbances and transient responses, which can damage equipment. Further, isolation transformers provide electrical isolation from external sources. As a result, the user should weigh these benefits as additional reasons to choose an isolated transformer over an automatic transformer.
When installing the drive, it is necessary to comply with all associated regulations and rules. As a result, all inputs must have an input disconnect that is either in sight of the drive or has padlock capabilities. It is important to ensure that the disconnect can accommodate any currents associated with the input. The user must wire the disconnect in the primary drive isolation transformer circuit.
