Energy efficient supercapacitor cell balancers include over-voltage protection
The precision dual-channel SABMBOVP2XX family of products automatically balances supercapacitors with the addition of over-voltage protection (OVP). The result is energy-efficient supercapacitor balancing, ideal for products that require low-loss energy power, leakage current regulation, and OVP. Supercapacitor cells typically operate at a nominal recommended working voltage. However, voltages that exceed the maximum rating for a […]
Programmable ac power sources now include 18-kVA model
The Asterion 12K3 supplies ac and dc output power up to 12,000 VA or 12,000 W, and the Asterion 18K3 supplies up to 18,000 VA or 18,000 W. Both units come in a 14U chassis and can supply single- or three-phase output power. Like the lower-power 1U, 2U and 4U models, Asterion Models 12K3 and […]
