NewTrend · adjustable voltage protector
Product overview
NewTrend PS8-01 provides adjustable overvoltage and undervoltage protection with automatic recovery for AC 220V line-to-neutral circuits. Its single digital display shows supply voltage; this model does not provide an overcurrent protection setting. Choose a 32A, 40A, 50A, 63A or 80A AC-1 version and the factory upper- or lower-incoming wiring configuration. The 36mm DIN-rail unit has adjustable voltage-fault and reconnection delays.

Operation
- Select the rated-current version and the U (upper incoming) or D (lower incoming) factory wiring configuration.
- Set the overvoltage threshold within 230-300V or OFF and the undervoltage threshold within 140-210V or OFF, according to the current catalogue.
- Set the voltage-fault action delay within 0.1-10s, power-up delay within 2-600s and reset delay within 2-900s. The function diagram illustrates a 2s power-up setting.
- The single voltage display and voltage-fault indicators support supply monitoring. Overcurrent protection and current display belong to PS8-02.
Typical applications
- Household-equipment protection against abnormal supply voltage
- DIN-rail distribution panels requiring adjustable voltage thresholds and automatic reconnection

Original protection timing diagrams, application wiring and dimensions
Follow the selected U or D incoming-line wiring. The current catalogue specifies a 2-600s adjustable power-up delay; the timing plot illustrates the 2s setting. This model provides voltage protection only; coordinate separate overcurrent and short-circuit protection for the installation. The upstream circuit breakers shown in the original application drawings are separate devices. Installation and wiring must be performed by qualified electricians.
