(£155.94 inc VAT)
In stock


The Vimpex Identifire PSU0011 EN 54-4 Approved switched-mode power supply has intelligent on-demand load sharing capability to provide exceptional flexibility. This allows rapid large capacity battery charging with either extended standby hold-up duration at light loads, or short high current peak loads where spare output capacity is diverted to battery charging.
