Ua = 60V
Ua max = 150V
Ia = 5.3mA
Ug1 = 0V
Ug2 = 45V
Ug2 max = 120V
S = 2.5 mA/V
P = 1.5W

All item(s) will be shipped by registered priority airmail, unless other agreement is set with the buyer.
DHL, FedEx or UPS shipment may be arranged too. In this case I would prefer if you have a customer number in the particular courier service.
