TM Epilson STS 2 2 1.4.1 PMM Plus and PMM Ultra 2 2 In the PMM Plus configuration, the input of the PMM cabinet is supplied by the output of the STS. The dual input distribution system accepts two independent AC input sources feeding to the STS. If the preferred input source power is not available, the STS will transfer to the alternate input source, avoiding interruption to the critical load. The output power is conditioned and stepped down to distribution voltage via an isolation transformer
