DIGITAL 3-PHASE LINE VOLTAGE MONITOR The DTP-3 is an automatic digital voltage monitor and control system. By continuously measuring the incoming line voltage, the DTP-3 monitor will detect voltages outside of the tolerance that you set. If these limits are exceeded, the response timer is started. This timer may be set to a long teems value to avoid nuisance tripping, or to a short time values to offer a higher level of load protection.
