PERFORMANCE

Discharge voltage (peak voltage)

Line to line: ±270 V min.

Line to ground: ±350 V max.

Maximum surge voltage

Line to line: ±650 V max.

Line to ground: ±900 V max.

(The maximum voltage that could pass through M-RESTER.

Protected equipment must be able to withstand this voltage

for very short time period.)

Response time: ≤ 0.1 μsec.

Leakage current:

Line to line: ≤ 100 μA @ ±160 V DC

Line to ground: ≤ 100 μA @ ±160 V DC

Discharge current capacity: 1000 A (8 / 20 μsec.)

(Modular jack contact welding is out of the scope of this

protection. (The surge protector still works even when

welding.))

Maximum load current: 500 mA

Internal series resistance: Approx. 0.1 Ω including return
