FAQ

How much power does it take to operate TSP® and charge Ultra-Capacitor?
Under the general operation condition, all unit consumes about 10 watts. Under 120V, this is equal to +/- 200 mA.
Can I replace Ultra-Capacitor only not the entire TSP® after the deterioration of Ultra-Capacitor?
Yes. Ultra-Capacitor doesn’t need maintenance and has longer life time than a battery, but even so, it still has a fixed life time. Once the warning message saying the battery’s life has ended shows, we provide the replacement service for Ultra-Capacitor.
How can I check the status of Ultra-Capacitor?
Users can monitor the status of Ultra-Capacitor and also, important information will be provided with various methods including special life time management function and charge/discharge voltage sensing.
How long does it take to get recharged for Ultra-Capacitor after the voltage sag?
It depends on the duration of the voltage sag and the discharge level after the voltage sag. It is uncommon for Ultra-Capacitor to get completely discharged. In most cases, it takes less than 1 second to be recharged to reach the available level. Depending on the capacity, it takes about 5 times of usual recharging time. And the charging time can be reduced by increasing the percentage(%) setting of TSP®’s charging current considering the power capacity of installed panelboard.
I’m worried that the resonance occurs in between Ultra-Capacitor and coils of Starters(e.g. pure reactive load).

Maximum resonance frequency can occur in the maximum reactive load. In this case, the calculated frequencies are as follows: in 500VA unit, fr = 4.75 Hz and in 3kVA unit, fr = 5.5Hz. In our calculation, there is a possibility of some kind of oscillation only when the resonance frequency is higher than the system frequency of 60Hz, but it never actually happened.

 

Under Full Bridge structure with Free-Wheeling Diodes, reactive energy returns every half-cycle after it is perfectly controlled. Self-oscillation doesn’t occur through bridge.
